Re: [mylyn-dev] Mylyn never lets the JobManager be idle?

[Stefanos.Zachariadis@xxxxxxx]

Apologies for the late reply, but I was on holiday. I've created bug
198241 for this issue.

(https://bugs.eclipse.org/bugs/show_bug.cgi?id=198241 )

I've also attached two patches for the classes under discussion.

Thanks,

Stefanos
