This is observed while trying to use Spark codebase using the 4.0.0-RC4. Spark current codebase uses scala 2.10.4 along with macro-paradise facility using paradise_2.10.4-2.0.1.jar which may be the problem as I see failure in the method org.scalamacros.paradise.Plugin.<init>(Plugin.scala:25) in the stacktrace. This crash happens repeatedly filling up "Error Log" window, which is probably expected. With this error, the current version of the IDE is not quite usable for the Spark codebase.

The PC should not load any compiler plugins when it's in compatibility mode (but they should be loaded when building).
