I've had a whole line of messes with java and .jar files. I've tried both OpenJDK (from software installer) and about three repositories for Sun.

/Desktop# java -jar -Xmx1024m ss.jar
Exception in thread "main" java.awt.HeadlessException
            at         java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:173)
            at java.awt.Window.<init>(Window.java:476)
            at java.awt.Frame.<init>(Frame.java:419)

            at org.powerbot.bd.<init>(Unknown Source)
            at org.powerbot.Boot.main(Unknown Source)

Two separate errors:

~/Desktop# ./ss.sh
[SEVERE] org.server.Boot: Default heap size of 490m too small, restarting with 768m

and about 30 different crashes were it just "aborts" with a huge file dump.

Each time I've tried something a little different, whether it be updating Java or just changing -Xmx1024 to -Xmx1024m to get rid of the heap.

Personally I think it has something to do with OpenVZ, but Google hasn't saved me this time, I need someone who can get to the bottom of my problem.

java -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

is my current install.

Running ss.sh gives me: (I'd post the entire log but its long)

I'm willing to let someone who knows what they are talking about view it and try and sort this out. Any help would be appreciated, I've about pulled all my hair Googling to no avail.
