The install may fail with a "JVM not found" error if the installation directory has the set-group-ID bit set. If this happens, then the <install location>/log.txt file will contain an error similar to:
An error occurred attempting to copy the current JVM: ServiceException: (error code = 399; message = "Command failed: '/bin/chmod 775 <install location>/uninstall /JRE-1_4 ' rc = 1 Error message: chmod: not all requested changes were made to <install location> /uninstall/JRE-1_4
If you retry the install a second time, it succeeds.
