NoClassDefFoundError: Could not initialize class test.framework.Terminal in all tests #38

Closed RomanLangrehr closed 9 years ago

RomanLangrehr commented 9 years ago

On my computer all tests fail because of an NoClassDefFoundError: Could not initialize class test.framework.Terminal.

jGleitz commented 9 years ago

I booted to Windows and now get the same error. I'm looking into it in the moment.

@RomanLan: Does your first failing method (red cross) have an error like this, too?:

@jGleitz Yes

jGleitz commented 9 years ago

@RomanLan: Does c3834fe solve this for you, too?

MartinLoeper commented 9 years ago

@jGleitz I still get an error message running the tests on Windows, too.

RomanLangrehr commented 9 years ago

On my computer it seems to work now.

jGleitz commented 9 years ago

@RomanLan: Glad to hear!

jGleitz commented 9 years ago

@MartinLoeper: Even with c3834fe? If yes, is there any error message (except for incomplete) that is different from this one?

MartinLoeper commented 9 years ago

@jGleitz I installed the latest testsuite minutes ago and receive the NoClassDefFoundError for every test. Only for incomplete the error does not happen. Every exception stack trace does reference test.TestObject.run(TestObject.java:634) as the cause.

jGleitz commented 9 years ago

Screw it. I cannot reproduce that. Could you please:

Better, copy anything from elementData to the last element and paste it here. Mine looks like this:

I do not get it... When I try to examine elementData, I get: [null, null, null, null, null, null, null, null, null, null].

jGleitz commented 9 years ago

Oh wonderful. What exact system are you running? OS & Java Version.

MartinLoeper commented 9 years ago

Win7 with Java 8.0_25.

@MartinLoeper Do you use Google Hangouts or another software supporting screen sharing? It would be nice to debug this on your machine, if you'd allow me to.

MartinLoeper commented 9 years ago

yes, ok, let's do it

MartinLoeper commented 9 years ago

Allright, I finally solved the error! It was located in MockCompiler.java (l.116). The default Java installation folder is "C:\Program Files (x86)\Java" in my case.

jGleitz commented 9 years ago

Oh, you have 32bit. Didn't think of it. I'll fix this.

Nevertheless, a error message

Your system does not provide a Java Compiler. It's Windows but we can't find your Java installation!

should be printed!

MartinLoeper commented 9 years ago

Yes, it was printed. I did not recognize it the first time. Sorry for that.

@MartinLoeper Please check if #58 solves this for you!
