Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server OSGi Applications with Java 7 * **************************************************************** * PROBLEM DESCRIPTION: A Java VerifyError occurs due to ASM * * incorrectly manipulating a class. * **************************************************************** * RECOMMENDATION: * **************************************************************** Internally, the ASM library is used to perform class bytecode manipulation. One requirement of Java 7 is that it contains a StackMap table to assist with class verification. The version of ASM in use contains a defect that causes the modified class to have an incorrect StackMap table, and this causes a java.lang.VerifyError to occur when loading the class. This can happen when methods in the class make use of multi-dimensional arrays.
Problem conclusion
The ASM library has been updated with a fix that correctly generates the StackMap for methods that make use of multi-dimensional arrays. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.3.
