I have a problem with the Eclipse 2018-09 JEE version causes the IDE to be unresponsive for longer time. Sometimes it doesn't recover at all. I even created a new workspace but it doesn't take long before the same problem occurs. It is getting very frustrating.

Any ideas on how to fix it?

There are MANY instances of both the Interrupted and the Timeout exception in the log:

    As far as I know, that's a bug that has been fixed some time ago. Please [upgrade](https://wiki.eclipse.org/FAQ_How_do_I_upgrade_Eclipse_IDE%3F#Always_enable_major_upgrades). You are two releases behind. – howlger May 24 '19 at 09:15

    This looks related to the version of the Spring Tools you have installed. Also update those. – nitind May 24 '19 at 13:14
