Performance issue on large grails gradle multi project build

Hi,

we had massive performance issues on our large grails multi project. The problem occurs every startup or if we change something in the gradle.properties.

The problem is unrelated to OS or machine.

After investigation, we found out, that every module starts a java thread with`JetBrains/Toolbox/apps/IDEA-U/ch-0/231.8109.175/IntelliJ%20IDEA.app.plugins/groovy-grails/lib/groovy-grails-rt.jar!/idea-injected-traits.groovy`.

Which lead to 78 additional java threads which are freezing nearly the complete system.

It would be nice if we somehow can limit the max thread count to prevent the system from freezing.

Start by reproducing the reported startup and gradle.properties-change behavior in a large Grails multi-project build, then inspect the referenced groovy-grails-rt.jar and idea-injected-traits.groovy path. Done means the build no longer creates one excessive Java thread per module or freezes the system, with the thread count appropriately limited.
