Hi all

Please reference

The conversation was stopped by fail, but my colleague found setting
LD_PRELOAD is usable in his environment.
So, please test with below.

% export LD_LIBRARY_PATH=/opt/jdk1.5.0_09/jre/lib/amd64/server:/opt/jdk1.5.0_09/jre/lib/amd64
% export LD_PRELOAD=/opt/jdk1.5.0_09/jre/lib/amd64/libzip.so 

Best regards
