  • ClassCastException net.sf.cglib.proxy.Enhancer$EnhancerKey$$KeyFactor yByCGLIB

    We are using:

    -- (m4)
    -- spring 2.5.2
    -- cglib-nodep 2.1_3

    Periodically, we see a java.lang.ClassCastException per below:

    net.sf.cglib.proxy.Enhancer$EnhancerKey$$KeyFactor yByCGLIB$$7fb24d72 incompatible with net.sf.cglib.core.KeyFactory

    at java.lang.J9VMInternals.initializeImpl(Native Method)
    at java.lang.J9VMInternals.initialize(J9VMInternals.j ava:196)

    We bounce our server, and the error is resolved. Next install; however, will sometimes recreate error.

    Any ideas?

    Found issue

    We found issue and is a result of bug in cglib when parent_last class loading is used. Opened issue with cglib: ClassCastException in KeyFactory$Generator.create
