**Attach or link to relevant artifacts**

[TestInvokeDynamic.jtr.xml](https://github.com/user-attachments/files/25130503/TestInvokeDynamic.jtr.xml)

Start by rerunning TestInvokeDynamic.java with a standard Grinder job on JDK8 linux-arm and review TestInvokeDynamic.java at line 249. Trace the NullPointerException through Locations.java and JavacFileManager.java using the provided console output and artifact. Done means the test no longer fails on the reported ARM machine.
