There is a lot of output and does seem to overwhelm the java -XshowSettings output with detail that I wouldn't expect by default.  It's effectively printing conf/java.security and enumerating all the capabilities of the providers and cipher suites. So I think I agree with Sean's suggestion to require the :security sub-option for the detail. We could potentially do this for the available locales too. The -XshowSettings output could include a message at the end about using -XshowSettings:detailed or some such sub-option for more detailed output.

In passing, it looks like some of the output is going to stderr, some to stdout, so you might want to check that. Also StringTokenizer is legacy, I don't think we want that in the java launcher code, it looks like it just needs String.split.
