Another javac issue

[Christian Humer]

Hi Stefan,

We haven't seen this yet as far as I know. You get some deprecation
warnings when compiling truffle, that you shouldn't get. Is your truffle
version patched?

Did you try to remove the suppresswarnings that cause the problem?
Otherwise, try to isolate the bug and report it to the javac guys.
