I do not see a problem to integrate such changes, since I assume you
will plan to backport it to jdk8. But later in jdk9 however probably it
will be better to move such information to the configuration file
I have one note about the fix: the usage of libaudio.exists() vs
defaultSoundFont.isFile(). I think we should use the same call in all
cases, the question is which one. Also it is interesting should we check
that the file is readable.
