1，经常在后台Synchronizing script resources with tern server ，然后OOM，
解决
把JBoss Tools Java Standard Tools Tern.java Adapter 给卸载掉

I have this problem also. I wonder about Help->Installation Details, and then UNINSTALL the JBoss Tools Java Standard Tools Tern.java Adapter. Will that fix the problem?
2、一打开eclipse，就Download quickstarts list，还没解决，好像可能是BUG

Thank you for the details.I could replicate the issue at my end. The start up error is caused by one of the installed JBoss Tools components.I have filed a bug for the dev team to investigate further. We will keep you posted about the fix.
