Local fix

  • The issue can be worked around by having the missing class on
    the class path
    

Problem summary

  • The NoClassDefFoundError is thrown erroneously when we call
    getAnnotation on a missing dependent class.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR1
    .
    The JVM has been fixed to correctly display TypeNotPresent in
    such cases.
    .
    To obtain the fix:
    Install build 20111108 or later
    

Temporary fix
