changing binary format to java 1.6 fixes the problem - unit tests pass.

note - non-enhanced classes work locally in java 1.7 format (pass jUnit tests), but then give similar error when run under GlassFish ..

steps to reproduce - open your Guestbook sample application in NetBeans, open project properties, change source/binary from 1.6 to 1.7, change compiler to 1.7, clean, build and deploy to GF - see error as below:

Thank you for this report.

Please try build 2.2.9_10 that should enhance correctly Java 1.7 class files.

I just upgraded to 2.2.9_11. I am using JDK 1.6.0_24. I'm not planning on upgrading to Java7 right now.

I now get the following exception in my client trying to connect to the server:

Unfortunately the Enhancer fix was broken.

Build 2.2.9_12 fixes it and in addition also applies the new addition only to class files that have been compiled for Java 7.

Thank you for this report.
