* This tests for various things as follows :
* Ensures that :
* 1 . uneccessary execs do not occur
* 2 . the environment is pristine , users environment variable wrt .
* LD_LIBRARY_PATH if set are not modified in any way .
* 3 . the correct vm is chosen with - server and - client options
* 4 . the VM on Solaris correctly interprets the LD_LIBRARY_PATH32
* and LD_LIBRARY_PATH64 variables if set by the user , ie .
* i . on 32 bit systems :
* a . if LD_LIBRARY_PATH32 is set it will override LD_LIBRARY_PATH
* b . LD_LIBRARY_PATH64 is ignored if set
* ii . on 64 bit systems :
* a . if LD_LIBRARY_PATH64 is set it will override LD_LIBRARY_PATH
* b . LD_LIBRARY_PATH32 is ignored if set
* 5 . no extra symlink exists on Solaris ie .
* lib / $ arch / libjvm . so - > client / libjvm . so
* TODO :
* a . perhaps we need to add a test to audit all environment variables are
* in pristine condition after the launch , there may be a few that the
* launcher may add as implementation details .
* b . add a pldd for solaris to ensure only one libjvm . so is linked
