When AndroidX upgraded to AGP 8.3.0-alpha02 we encountered this extra text output by our build here:

> Task :compose:ui:ui-tooling:lintAnalyzeDebugUnitTest
Could not load custom lint check jar file $GRADLE_USER_HOME/caches/transforms-3/aa5275c9600e095256328a1bc040e479/transformed/material-1.0.0/jars/lint.jar
java.lang.ClassCastException: class java.util.HashMap$Node cannot be cast to class java.util.HashMap$TreeNode (java.util.HashMap$Node and java.util.HashMap$TreeNode are in module java.base of loader 'bootstrap')

It could be nice if this stacktrace could be not shown - we're thinking it might be triggered by concurrent accesses.

We're probably going to add a temporary exemption for this extra output in b/300090060

Lint can be run in multiple threads via AGP. See b/278767328#comment27. I guess this is probably a case where this was not expected. I.e. the cache property in JarFileIssueRegistry.Factory is probably not thread-safe.
