Gregory Williams commented on NETBEANS-3802:
Added *Affects Version/s* of {{{}12.5{}}}, since I've just seen the same issue
there, but probably affects at least all versions between the original report
(11.2) and that.

[jira] [Created] (NETBEANS-5705) Java editor uses obsolete lexer token sequence
Gregory Williams created NETBEANS-5705:

Summary: Java editor uses obsolete lexer token sequence
Key: NETBEANS-5705
URL: https://issues.apache.org/jira/browse/NETBEANS-5705
Project: NetBeans
Issue Type: Bug
Components: java - Editor
Affects Versions: 12.3
Environment: *Product Version:* Apache NetBeans IDE 12.3
*Java:* 1.8.0_272; OpenJDK 64-Bit Server VM 25.272-b10
*Runtime:* OpenJDK Runtime Environment 1.8.0_272-b10
*System:* Linux version 5.8.18-100.fc31.x86_64 running on amd64; UTF-8; en_GB
(nb)
*User directory:* /home/redacted/snap/netbeans/common/data/12.3
*Cache directory:* /home/redacted/snap/netbeans/common/cache/12.3
Reporter: Gregory Williams
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:
{code:java}
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which is no longer valid.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.
