First of all: I'm posting here because I'm having a suspect about Jetty being the cause through Logback, but:

  • I'm not using Jetty in my Eclipse installation, so it seems like an embedded instance is started automatically I don't know exactly for what purpose
  • I'm not 100% sure the problem is in Jetty+Logback, but the thread dump seems to reveal that's the only "activity" in progress

Recently it happens that just leaving my Eclipse instance running, without doing anything (actually, I'm surfing the web, reading e-mails, etc.) at certain point I hear the CPU fan spin a lot. Looking at Task Manager, I see my Eclipse instance eating about 12-14% CPU constantly (which I guess is just a 100% busy thread of my 4-core + Hyperthreading i7 CPU). This goes forever and does not stop until I restart Eclipse. I'm attaching a thread dump, which reveals that nothing is in progress, except for a Jetty instance trying to append to a Logback log.

Any suspect?

I'm using Eclipse 4.5.1 (M20150904-0015). The list of "Installed Software" shows:

This is not reproducible, Thread dump shows normal thread behavior in Jetty.

Open a fresh bug if you can show a reproducible testcase.
