The HPROF parser Exception

!ENTRY org.eclipse.osgi 4 0 2022-05-05 12:18:51.182 !MESSAGE Application error !STACK 1 org.eclipse.mat.SnapshotException: The HPROF parser encountered a violation of the HPROF specification that it could not safely handle.

You can modify the version in https://github.com/eclipse/jifa/blob/master/backend/heap-dump-analyzer/eclipse-mat-deps/eclipse-mat-deps.gradle to choose other versions of mat, I think 1.10.0 is supported, but not very sure.

[IcanDoItL]

I try it, but My Local Gradle version is 6.6.1,so when ./gradlew buildWorker FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring project ':backend:heap-dump-analyzer:eclipse-mat-deps'.

java.lang.reflect.InvocationTargetException Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.
