>From what I remember of the issue, some JREs were holding onto memory that should have been deallocated, which eventually fills the memory pool and crashes, while the good JREs kept their memory usage fairly constant. The issue was solved in Sun's java before the default java debian/ubuntu install, but I think it got solved in that one also in more recent versions. If all else fails, you could try updating to the latest available JRE.
Note that you may have multiple versions of java installed, and may need to configure which one is used by default, for instance http://java.dzone.com/articles/choosing-java-version-ubuntu .
