Setting LD_LIBRARY_PATH appends java.library.path, but passing
-Djava.library.path to java overwrites java.library.path [1]

sun java doesn't use a .properties file to override the system
defaults on start up. IBM's java does [2], but there is no
corresponding feature in sun java that I can find (and others
apparently can't find it either[3].)
I created a patch (attached) for the debian packaging which replicates
what is done with javaws. I have a template in debian/ which is filled
in to point to the correct directory, then is installed into
/@BASEDIR/jre/bin. The original java binary is moved to java.real and
is called by the wrapper after properly setting LD_LIBRARY_PATH

#java channel on freenode Feb 12,2009:
[01:43:28] <nog_lorp> is there a way I can configure JVM system
properties globally for Sun Java?
[01:44:11] <nog_lorp> IBMs java docs mentions the
SystemDefault.properties file, but that is not mentioned anywhere by
sun
[01:44:15] <nog_lorp> and doesn't work
java_library.patch
