Test with PowerMock fails when run on java 1.7.0_65 #504

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
- Have a unit test annotated with @RunWith(PowerMockRunner.class) 
@PrepareForTest(MyEndpoint.class)
   and use mockStatic(MyEndpoint.class); in the setUp method of the test.

What is the expected output? What do you see instead?

I would expect that the test runs normally and without error as it did before 
with older java versions (1.7.0_55 works).

Instead the test fails with the following stacktrace:

Most likely, it's a JDK bug

seems to exist with PowerMock...

This is a show-stopper for our use of PowerMock. Are there plans on the

There is a work-around for this issue: run the junit tests with a '-noverify' 
jvm argument

I added a comment to https://issues.jboss.org/browse/JASSIST-228 that suggest 
another workaround for this problem. (unfortunatelly they are maintaining their 
server currently and i cannot quote myself from there)

However, if you still feel that you need to have your java class file verifyed 
(hence -noverify is out for you) you can use -XX:-UseSplitVerifier option when 
you start your tests.

And if you are like me, and start your tests with maven, then you need to add 
something similar to your pom.xml
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.10</version>
                <configuration>
                    <argLine>-XX:-UseSplitVerifier</argLine>
                </configuration>
            </plugin>
        </plugins>
    </build>

You must avoid branching before a super call.

You could change the ExprEditor in the MainMockTransformer Line 269-273 to use 
no branching. Or use branching only if really needed and verify it. (I don't 
know how to call the JVM verifier, using CtClasses 
.toClass().getDeclaredConstructors() would throw a Exception) From thereon you 
could show a nice error message explaining the details.

Just disable constructor mocking if 

        CtClass ctClass = ClassPool.getDefault().makeClass("TestForBadOperandWhenInvokingInit");

        //      java.lang.VerifyError: Bad operand type when invoking <init>
        ctClass.addConstructor(CtNewConstructor.make(new CtClass[0], new CtClass[0], "{if (1 != 2){ super();}}", ctClass));
        final Class<?> clazz = ctClass.toClass();

        clazz.getDeclaredConstructors();

throws an Exception and log it out. There is already a fix commited for the 
next JDK version, so this bug should not haunt us for long.

I don't believe that this is a bug in the JDK. Oracle has decided to make their 
byte code verification rules stricter-details here 
http://www.takipiblog.com/oracles-latest-java-8-update-broke-your-tools-how-did-
it-happen/.

I also don't believe that there will be a fix in future versions of java as it 
is not a bug it is a feature. Oracle Java 8u20 still has this "feature".

The suggestion to use the SplitVerifier may work in Java 7 but I believe that 
the SplitVerifier has been removed in java 8. There is the option to turn off 
verification completely for tests (ie -noverify) but the confidence is lost 
that your code will work in production without this option and I don't think 
disabling bytecode verification in production is a great idea.

The OpenJDK team may of reverted the change but I don't think oracle will be so 
nice :)

The only real option is to fix the offending PowerMock class.

GoogleCodeExporter commented 9 years ago 
If you're right we need to figure out a way to fix it. How it works now is that 
before the call to super the MockGateway is invoked to decide whether or not to 
call the super method or call another constructor (generated by PowerMock). 
This is used for constructor suppression (suppress(constructor(X.class))) if I 
remember it correctly. All method invocations, field invocations etc works in 
the same way (they all ask the MockGateway if they should continue or replace 
the call with a mock). For constructors I'm not sure how to solve this unless 
we insert this if statement (which I believe is the cause of the error) before 
the super call in the constructor byte-code. If you have any ideas for a 
workaround I would be really happy. 

A really ugly work-around would be to let the user somehow configure PowerMock 
not to byte-code manipulate constructors (if you don't need to use this 
functionality). That way I assume that some errors can go away but PowerMock 
will be left in a degraded state. Not sure if I want to go down this route.. 
However I've been thinking about implementing something like this before to 
speed up the byte-code manipulation (such as turing off field interception 
which is quite slow and not used very often afaik).

ctClass.addConstructor(CtNewConstructor.make(new CtClass[0], new CtClass[0], 
"{if (1 != 2){ super();}}", ctClass));

Looks like this line makes new constructor with code. Right?

{if (1 != 2){ super();}}". Not sure why 1 != 2 check is needed but this is what 
is causing the problem. the first thing you have to invoke in the constructor 
is the super constructor. So probably it should be something like this 
{super(); if (1 != 2) {}}

GoogleCodeExporter commented 9 years ago 
This might be the simplified version you could use to reproduce the error.. 
The original code is:

code.append("if(value == 
").append(MockGateway.class.getName()).append(".PROCEED) {");
code.append("   $_ = $proceed($$);");
code.append("} else {");
code.append("   $_ = 
").append(getCorrectReturnValueType(returnTypeAsCtClass)).append(";");
code.append("}}");

It is there to decide if another constructor should be called.. that code must 
be changed to call super() first. YOu would loose the ability of on demand 
constructor mocking.. or you would have to replace the mocked constructors 
during mocking.

So I had a chat to some of of the developers here and I've learnt that the 
Oracle JDK is built on top of OpenJDK so any fixes made in OpenJDK will find 
their way through to the Oracle JDK. Therefore this "feature" has been reverted 
as per this issue https://bugs.openjdk.java.net/browse/JDK-8051012 and we just 
need to wait for the relevant version to be released. For java 8 it looks like 
8u20 b31 has it fixed, the latest public release is for 8u20 is b26 so the fix 
hasn't been released yet. I couldn't find a release date for build 31 anywhere.

Perhaps you have different test scenarios? It works in some cases but fails in 
others?! But then it could be another issue altogether?

For reference, the bug that is apparently fixed is:

http://bugs.java.com/view_bug.do?bug_id=8051012

It is referenced from this page:

http://www.oracle.com/technetwork/java/javase/2col/7u72-bugfixes-2298229.html

I presume the bug isn't marked as resolved, because update 72, is some weird 
sort of halfway release, where Oracle recommends you use update 71 unless you 
need fixes from 72:

This issue is present for me I tried 72.
It works with the UseSplitVerifier option. But, that will be deprecated:
https://code.google.com/p/powermock/issues/detail?id=504

So, unless this is fixed, will have to migrate to a different framework. I'll 
take a look to the code later on to see if there is something I can help with.
