So I tried out the patch (took some time to build ppa:james-page/junk)
and did some more digging when it did not appear to work.
I managed to capture a stacktrace when the issue occured:
java.lang.UnsatisfiedLinkError: Unable to load library 'pam': libpam.so: cannot

So it looks like the issue (or maybe one of them) is actually in libjna-
java; I'm pretty sure that openjdk may exhibit the same symptoms but the
issue reading libpam.so is generated outside of openjdk.
I'll look into the specific library to see what its doing - suspect it
something horrible with guessed paths but it may be related to the
java.library.path variable.
