See similar web issue 59495 (probably a duplicate?)

Should be P0, even my whole computer is couple minutes completly dead.
Comment 3 Tomas Zezula 2005-06-01 15:50:12 UTC 
Rather then creating a new priority you should attach the thread dump to find
out what is the problem. It can be eg. gc

Comment 5 Tomas Zezula 2005-06-01 18:58:30 UTC 
The J2SEPhysicalViewProvider.J2SELogicalViewRootNode listens on the Sources more
than 7000 times using the weak listener. I am not sure how many instances of
J2SEPhysicalViewProvider.J2SELogicalViewRootNode exists. If there are 7000
J2SEPhysicalViewProvider.J2SELogicalViewRootNode or few
J2SEPhysicalViewProvider.J2SELogicalViewRootNodes listen many times on Sources.
