This change should fix#13 by releasing the string buffer from the JVM after we
convert the string to a Go string. However, I've been having a lot of trouble
building the tests on Linux, and I've run out of time to keep messing with it.
I'm posting this patch in the hope that someone else is better positioned to
validate it. Please do not merge this unless you can verify that it works
properly.
