Game programming with Java in Linux

presently I hv been craving little game programming. I primarily use Linux and was shocking if there're any best graphics libraries for Java development on Linux? Google didn't turn up very much useful info on the subject.Also would other language be superior? i wish to avoid using python -- Ruby and Java are my two favorite languages. There doesn't appear to be much talk about game programming on Linux in general unfortunately.Any suggestions/resources? easy portability or cross-plat

This class also maintain cache for increasing performance. public class FooTableGateway { Map id2foo = new HashMap (); public void getFoo (int id) { if (id2foo.containsKey (id) { return id2foo.get (id); } String query = "select ..."; Connection cn = null; Statement st = null; ResultSet rs = null; try { cn = DBUtils.getConnection (); st = cn.createStatement (); rs = st.executeQuery (query);

What causes a JRE 6 JVM code cache leak?

Since switching to JRE 6 my server's code snippet snippet cache usage (non-heap) keeps growing indefinitely. My application creates a lot of classes at runtime BUT these classes are successfully unloaded during the GC process. I can see these classes getting unloaded in the gc logs and also the permGen usage stays constant. I specifically make sure in my code snippet snippet that these classes are orphaned once I am finished with them and so they perfectly get garbage stored from permGen.The code snippet snippet cache howe
