Message Oracle ORA-29545 - badly formed class: string

ERRORbadly formed class: string
CAUSEAn attempt was made to create a Java class object with bytecodes that were rejected by the Java verifier.
ACTIONIt is possible that an attempt was made to create the Java class from a damaged class file, in which case the CREATE should be reattempted with a correct class file. It is also possible that the message is the result of using - in the resolver so that the verifier could not check the correctness of some code. In that case, the class needs to be created with a resolver.
