Description Pascal Rapicault CLA 2009-02-18 21:04:19 EST 
Because of some speed problems, I did a thread dump of the VM (see attachment) to discover that I had a lot of threads called "Timer-<someDigits>" for which I could not identify the provenance.
I'm opening this bug here for two reasons:
- Identify the owner of the "Timer-*" threads as this looks like a bug.
- Remind everyone that threads are not free and in eclipse we have a thread pool capability with the Jobs API.

At the time I had installed:
- SDK
- Mylyn bugzilla connector
- Subversive, SVN Kit and Java HL
- Eclipse releng tools
- Eclemma

VM dump
Comment 2 Steffen Pingel CLA 2009-02-19 14:23:24 EST 
Mylyn still uses a single TimerThread in version 3.0.x which probably shows up in the stack dump. All usages of java.util.Timer in Mylyn will be replaced by jobs for the next release (and Galileo): bug 233590.
Comment 3 Pascal Rapicault CLA 2009-02-20 23:29:40 EST 
Given that I'm using Mylyn 3.1 20090202, the threads I am seeing are probably the Mylyn ones.
Closing as a dupe for now.
