`ConcurrentModificationException` in `PluginLogger` in multi module gradle project

[theborakompanioni]

When building a multi-module Java project with gradle a ConcurrentModificationException exception is thrown sometimes.

gradle settings:

org.gradle.configureondemand=true
org.gradle.parallel=true

The issue disappears with org.gradle.parallel=false.

Logs:

This should be fixed in the latest snapshots. Would you mind giving them a spin?
