Many JCK lang tests, such as these fail with IAE errors like this one:

java.lang.IllegalAccessError: tried to access method javasoft.sqe.tests.lang.annot121.annot12101m02226022.annot12101m02226022$TTest.<init>(Ljavasoft/sqe/tests/lang/annot121/annot12101m02226022/annot12101m02226022;)V from class javasoft.sqe.tests.lang.annot121.annot12101m02226022.annot12101m02226022

Failing tests include lang/ANNOT, lang/BINC, langCLSS, lang/EXPR and others.
