Many exceptions in 2016.3.174 关注
com.intellij.diagnostic.MessagePool$TooManyErrorsException: Too many IDE fatal errors. Monitoring stopped.
Exception report IDs: 1195867 to 1195873
I'm also getting odd red stuff (code marked as invalid syntax), but I can't trust it because it's very inconsistent.
Please try 2016.3.192, it fixes incompatibility with the new IDEA 2016.3 EAP.
Just updated to 179, same thing.
Same thing in 183, error highlighting basically stops in the middle and an exception is thrown that a method in Idea is missing. I filed the report in IDEA.
