jtreg currently provides online help using JavaHelp, but the information provided is either out of date (the FAQ) or is better provided elsewhere (tag spec, command line help). The novelty of "online help with search" has worn thin.

We cannot completely remove the need for JavaHelp at this time, since JTHarness itself depends on JavaHelp, but we can reduce the need when building jtreg to a "passive" use to just copy jh.jar into the jtreg image. As a side effect, we do get to eliminate a build-time dependence on Xalan, which was used to build the search index for the jtreg online help.

A corollary of this is that the -onlinehelp option will no longer be available, to open the online help.
