Description

Hello,

I'm not sure, but I edited the class name, then created a new class and started editing it. This problem was probably caused by one of these activities.

java.util.ConcurrentModificationException: Caller uses obsolete token sequence which is no longer valid.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=90, tokenList.modCount()=91, rootModCount=91java.util.ConcurrentModificationException: Caller uses obsolete token sequence which is no longer valid.

module that calls lexer's code e.g. java, php etc. but not the lexer module itself. at org.netbeans.api.lexer.TokenSequence.checkValid(TokenSequence.java:784) at
