Bug Report against outdated lexer's code

### Apache NetBeans version

Apache NetBeans 18

### What happened

There is a notification that is a bug. when I compile a Java code. I thinks the program itself suggest that i must report this lexer's code issue, I dont know about it but, It is a concern to its own compiling problem


### How to reproduce

Just look at this type of code issue.

I just run some code that inolves connecting to mysql-connector php
I think It just want to notify that these codes are something obsolete or no longer valid and it needs to be reported.
Everytime I run the code related to JDBC mysql Connector. Then suddenly the suggestion pop out is always related to com.sun.source.

```
java.util.ConcurrentModificationException: Caller uses obsolete token sequence which is no longer valid.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=4, tokenList.modCount()=5, rootModCount=5
Please report a bug against a module that calls lexer's code e.g. java, php etc. but not the lexer module itself.

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Windows 10 version 22h2

### JDK

JDK 17

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

It does occur when I import the mysql-connector for php database.

### Are you willing to submit a pull request?

Yes

Start by reproducing the exception while compiling JDBC MySQL Connector code, then read TokenSequence.java, TokenList.java, and SemanticHighlighterBase.java at the stack-trace locations. Trace which Java editor operation invalidates the token sequence; done means the reported exception no longer appears for the reproducer and the responsible caller is identified.
