Play 2 template editor CPU usage

[Nils Weinander]

I have problems with the Play 2 template editor in Scala-IDE. Current setup:

* Eclipse Oxygen.1

* Scala-IDE 4.7.0

but I have experienced the same with other versions. Whenever I open a Play template in the editor, CPU usage skyrockets to 300%+, then falls back to ~150% and stays there, even when idle. Closing all editor tabs does not help either.

Is there anything I can do about this? I have tried increasing Eclipse memory allocation (-Xmx 1G to 2G), but that made no difference.

Sorry, forgot to mention the rest of the environment:

* Ubuntu 16.04

* OpenJDK 8
