After migration from Eclipse 4.3 to Eclipse 4.4.1, I encounter sometimes Out Of Memory error in one test suite (1 out of 3 times).
Analyzing Heap dump I can notice that a lot of memory is consumed by UISynchronizer (Problem suspect 2 and 3 are caused by UISynchronizer too)
/*** planned to insert an image but not found a working Free Hosting site yet...***/
There is a lot of Objects kept in pendingStartup list attribute (almost 2000), mostly of 3 types:
If I look to the Threads stack I didn't notice any lock which could explain that all these "pendind startup" Runnables are kept in memory. I suppose that it means that all these Runnables were not executed yet.
Which threads/Which objects are responsible to execute all items of this list?
How can I investigate why elements of this list are kept here? (and so not executed yet?)
Thanks for any help on understanding or debugging this issue.
