Local fix
Problem summary
The problem is caused by anonymous inner classes not being recognized as inner classes, which caused Class.getModifiers to return incorrect modifiers.
Problem conclusion
The JVM has been updated to treat anonymous inner classes as inner classes and Class.getModifiers returns the correct modifiers in all cases. . This APAR will be fixed in the following Java Releases: 7 R1 SR3 FP20 (7.1.3.20) 8 SR2 (8.0.2.0) 7 SR9 FP20 (7.0.9.20) .
