I think before we create another solution like gcj-exec, it is easier to maintain the current implementation of jarwrapper. I agree that gcj's handling of LD_LIBRARY_PATH and Multiarch could be improved but in my opinion there are other aspects about gcj which deserve even more attention. Most modern Java applications just don't work with it. I suggest to upload the fix for #764630 now. I just saw tony's email from the 21th. The current state on master is final. I haven't planned any further changes to jarwrapper. Please go ahead. Regards, Markus
