Sure enough, this fixed the problem. I just installed the latest Sun JRE and it is working now. Thanks for the suggestion! I would have never guessed.

Yes, that's the broken version of gcj.  I don't have a Centos machine here at the moment, but I think if you install OpenJDK and use the alternatives system to select that as the default JRE then that should fix things.

Hi Simon,

I recently installed Java with the yum package manager on our compute nodes, and our cluster is a Centos 6 environment. Here is what the results of "java -version" returned on the compute nodes:

"bash# java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.4 20100726 (Red Hat 4.4.4-13)

Is this version of Java too old? Perhaps I need to install the JRE manually?

Thanks!

Are you by any chance running an older version of gcj as your java version?  There is a known bug in some of these where they don't correctly configure the headless environment, even if the correct parameters are passed.  This causes exactly the kind of errors you're seeing.

If this is the case you'll need to install a more recent JRE (or update your path to point to one which is already present).

Simon.
