mbien opened a new issue, #6525:
URL: https://github.com/apache/netbeans/issues/6525
### Apache NetBeans version
Apache NetBeans latest daily build
### What happened
noticed while testing the jgit changes. While browsing git history in diff
view, the pom files sometimes fail to load and the exception is thrown. The
diff view remains empty when that happens.
```

### How to reproduce
unfortunately this doesn't seem to be always reproducible, still trying to
figure out why:
- clone https://github.com/apache/maven-indexer.git
- right click -> git -> show history
- right click on acf3329 -> diff to previews
- go through the poms and check if all diffs load, if it doesn't load,
check log
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
linux
### JDK
JDK 21
### Apache NetBeans packaging
Own source build
### Anything else
