maven fails on IBM JDK 1.5.0 with exception IllegalAccessException: Field is final

On Windows XP, and IBM JDK 1.5.0, maven 2.2.1 fails with the exception IllegalAccessException: Field is final. (See the complete stacktrace is at the end)

How to duplicate:
1. (IMPORTANT) Delete maven local repository at <user home>\.m2\repository directory completely!
2. Unzip myapp.zip
3. Run command "mvn package -e"

More info:
The exception will happen when maven trying to set value to some static final fields. Re-run the command will see another new exception (old exception will not happend again). If you try maven in debug mode (to debug it with Eclipse), the exception will NOT appear. The complete information about maven, JDK, etc. are in the attached file: ibm.output.txt. The other output file (sun.output.txt) is the successful result when running using Sun JDK 1.5.0

Root cause:
In StringSearchModelInterpolator.java of maven 2.2.1, there is a code snippet that tries to using Reflection to change values of fields (even if the fields are final)

Line 175:
fields[i].setAccessible( true );
Line 189:
fields[i].set( target, interpolated );

If fields[i] is a final field, on Sun JDK 1.5.0, the operation is successful but on IBM JDK 1.5.0, an exception will be thrown.
