StringIndexOutOfBoundsException with wicket-1.3.0-rc2.jar #7

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Run the attached Ant build script using "ant -d -f jjdebug.xml" ensuring
that the property setting the path to the wicket-1.3.0-rc2.jar file is
correct for the test system

What is the expected output? What do you see instead?
Should have generated a deps.jar file containing the contents of the wicket
JAR.  Instead, got a "java.lang.StringIndexOutOfBoundsException: String
index out of range: -3" as shown in snippet below.

What version of the product are you using? On what operating system?
Testing jarjar1.0-rc6 on a Win2K, SP4 system with JDK 1.6.0_03

Please provide any additional information below.

Got the following exception trace result in which it appears that during
visiting a field, PackageRemapper.mapPath() calls String.substring() which
throws the exception.

JarJar was able to work on many of files from the Wicket JAR but always fails 
when
attempting to use org/apache/wicket/validation/validator/StringValidator.class 
from
the Wicket JAR.

I've also replicated this with wicket-1.3.0 final, JDK 1.5.0_08-b03, WinXP SP2,
jarjar1.0-rc6.

I did a little debugging and found that the Exception is thrown when processing
org.apache.wicket.validation.validator.UrlValidator  

The Exception happens when visiting the VALID_CHARS field.  In UrlValidator the 
field
is defined as

private static final String SPECIAL_CHARS = ";/@&=,.?:+$";
private static final String VALID_CHARS = "[^\\s" + SPECIAL_CHARS + "]";

Inside jarjar, the Exception is thrown from
PackageRemapper.mapPath(PackageRemapper.java:84).  The method is called with a 
path 
value of "[^\s;/@&=,.?:+$]".  When it gets to line 84 it tries to do this

s = s.substring(0, s.length() - RESOURCE_SUFFIX.length()) + end;

Here s = "[L\s;" and RESOURCE_SUFFIX = "RESOURCE", so the code throws
StringIndexOutOfBoundsException.

This is fixed in SVN.
