FSF JRE location wrong?

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.0.6-1.2.fc4 Firefox/1.0.6 Description of problem: The "Java" page of the Options dialog lists the FSF JRE, which is nice - but the "Location" at the bottom of the dialog says "/usr". /usr/java, /usr/javac, etc are symlinks controlled by alternatives, so they may point to any number of JRE implementations. Could things get messed up if someone were to switch to a Sun alternative via "alternatives --config java"? I don't know if this "Location" is used for anything significant. If it is, perhaps it would be best to refer to /usr/lib/jvm/java-1.4.2-gcj, which is the equivalent of JAVA_HOME for the gcj-based JRE. Version-Release number of selected component (if applicable): openoffice.org-core-2.0.0-3.2.1 How reproducible: Always Steps to Reproduce: 1.Go to the Java page of the Options dialog, and look at the Location of the FSF JRE Additional info:
no it's right. it's the dir above the bin directory in which the "true" executable for the given jre was found, i.e. /usr from /usr/bin/gij
(In reply to comment #1) > no it's right. it's the dir above the bin directory in which the "true" > executable for the given jre was found, i.e. /usr from /usr/bin/gij Yes, I realize that. /usr/lib/jvm/java-1.4.2-gcj/bin/java exists and will always symlink to gij. But now I'm guessing that you're searching for gij, so I suppose what you're doing will always work as well. However, if OO.o always searches under /usr/lib/jvm it should find all of the installed JRE's and never have to special case gij. Running "alternatives --display java | grep priority" might even be a better way.
Only for systems that use jpackage and alternatives, it's the same code for solaris, windows, yada, yada. the gory search system is in OOO680_m3/jvmfwk/plugins/sunmajor/pluginlib. The gcj stuff is just one tiny subset of the full search thingy. Maybe there's an argument to add support for using alternatives when supported, I'll suggest it to the jvmfwk people.
