Description
On Solaris, if you set LD_LIBRARY_PATH_64 then that completely overrides any setting of LD_LIBRARY_PATH. If the prevailing environment defines LD_LIBRARY_PATH_64 then the launcher tries to defend itself by prepending its preferred library paths to LD_LIBRARY_PATH, as implemented in the fix for JDK-7029048. That will, however, have no effect -- the launcher should, in this case, prepend its preferred paths to LD_LIBRARY_PATH_64.

FWIW, starting in JDK 5.0 (JDK-4810347) on Solaris the launcher correctly checked the trio of LD_LIBRARY_PATH, LD_LIBRARY_PATH_32, and LD_LIBRARY_PATH_64 back when the launched needed to re-exec to get the runpath set correctly. The changes in JDK-6367077 removed this behavior.
