ORA-29552: verification warning: string

What triggered the Error:

An attempt was made to create a Java class object with bytecodes that caused the Java verifier to issue a warning.

What should we do to fix it:

is possible that the Java class was created 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.
