Snjezana Peco commented on JBIDE-20982:
---------------------------------------

I can't reproduce the issue on Linux and Windows.
Importing 200+ javaee7-samples projects takes a long time. Once they are imported, Eclipse/Java consumes 2+ GB RAM, but a minimal percent (<1%) of CPU.
I can't test on Mac. Try to test Eclipse Mars and some newer JDK.

> Steps to reproduce (on MacOSX):
> - import all WildFly Quickstarts (https://github.com/wildfly/quickstart)
> - restart the workbench
> - once all projects have been built and no job appears in the progress view, JBDS still consumes ~40% a CPU
