Problem summary

  • Error 'java.lang.ClassFormatError' is thrown by the JVM for a
    valid identifier during class verification. Validation of the
    identifier is done using Character.isJavaIdentifierPart(ch).This
    API returns true for the identifier which adheres to the JVM
    specification for naming convention of the class,methods or
    fields. However an error in the class verifier results in the
    above exception being thrown.
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR12
    .
    The JVM class verifier code has been fixed to correctly classify
    the characters in identifiers according to whether they are
    valid in class names, method names, or fields.
    .
    To obtain the fix:
    Install build 20091117 or later
