java.lang.VerifyError: JVMVRFY010 multiple jsrs use single return

Question

While using IBM I am getting following error. It is working fine with Oracle. I have my class compiled with Oracle and not IBM.

I an getting this error while calling a class through reflection. Running it through main method works fine.

Class aClass=ObfuscationUtility.class;
        Method[] methods = aClass.getDeclaredMethods();
        for (Method method : methods) {
            if (method.getName().equals(deobfuscated_method)) {
                method.setAccessible(true);
                try {
                    decryptedText = (String) method.invoke(aClass, encryptedText);

....

Any suggestions what mistake I may be doing.

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.
