    Description

      This has happened a few times whilst editing some Java 8 code, but I've not managed to pin down exactly which step/syntax it is that's causing it:

      java.util.ConcurrentModificationException: Caller uses obsolete token sequence which is no longer valid. Underlying token hierarchy has been modified by insertion or removal or a custom language embedding was created.TS.modCount=600, tokenList.modCount()=613, rootModCount=613
      Please report a bug against a module that calls lexer's code e.g. java, php etc. but not the lexer module itself.
