Hacking the OpenJDK

[Camel Aissani]

Hi Lillian,

Sorry to insist but I updated my repo and I still have the exception.
In my repo, I have a patch file icedtea-version.patch and is correctly
applied on these files :
openjdk/jdk/make/common/shared/Defs.gmk
openjdk/hotspot/src/share/vm/runtime/arguments.cpp

What can I do to identify and fix my problem?

Thanks,
Camel
