I’m setting up my JAVA_OPTS with: “-d64 -server -XX:+CMSClassUnloadingEnabled” and then some.
I thought the -d64 was to specify that the machine was 64bit or running on 64bit!?
This seems to work fine on Macs. When I tried it on Windows 7 using Cygwin to run the shell script, it breaks. If I remove the -d64, everything works fine.
I also did the same thing using windows batch files, the -d64 still throw the same error.
What could be the problem?
The
-d64option is Solaris/Linux specific. On Windows that option is not availableAs Mac OsX is linux-based, the option would work there. On Windows you will need to select the JVM by selecting the executable (the 64 bit/32 bit versions are separate installation) — either directly naming the executable or by properly adding its bin to the PATH environmental variable
