I am using Eclipse stand-alone, not from package, but I am observing the same behaviour. A quick test revealed, that the problem exists with the New Wave theme, but does not occur with the Human-Clearlooks theme. Haven't tried other themes.
To reproduce start Eclipse with the New Wave theme, Eclipse takes 100% CPU, use the control panel to switch to Human-clearlooks, and after a brief delay CPU usage falls down, then you can turn back to New Wave theme. This behaviour tends to reoccur after the back-and-forth theme switching can't pinpoint the reason though. I have an unconfirmed hunch, that this behaviour occurs when an unbound progress bar is displayed (the one that moves back-and-forth). Such a progress bar is available upon start-up, and also with CVS/SVN operations, possibly others. Ubuntu 09.04 Jaunty, upgraded from 08.10: AMD64 (!!!) Eclipse SDK, Version: 3.4.2, Build id: M20090211-1700 I am attaching a small file containing two stack traces: one from initially start-up Eclipse, and one after switching the theme. ** Attachment added: "Stack traces" http://launchpadlibrarian.net/25980097/stack_trace.txt -- Eclipse takes 100% CPU https://bugs.launchpad.net/bugs/334991 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
