Issue #1635: Enhancer: non-zero exit code at exceptions

Hello,

we have found that the enhancer returned an non-zero exit code on errors.

You can change this so that the error of the enhancers can be detected.

Thank you for this report. Starting build 2.6.1_04 the Enhancer exits with non zero code on errors.

Note that System.exit is now invoked (on errors) so calling Enhancer.main from a running program may terminate the JVM.

Thank you. It works.
