rmetzger opened a new pull request #11638: [FLINK-16973][tests] Add tooling for collecting jvm crash files URL: https://github.com/apache/flink/pull/11638 ## What is the purpose of the change A lot of tests are failing because of crashed JVMs. This PR will add some tooling to search the Flink directory for JVM crash files. ## Verifying this change This change has been tested here: https://dev.azure.com/rmetzger/Flink/_build/results?buildId=7072&view=results In this test, the "core" profile fails with an artificially induced JVM crash. A coredump + some debugging files are attached. There was a [previous discussion](https://github.com/apache/flink/pull/11372#discussion_r392367035) about this change. [I tried](https://github.com/rmetzger/flink/commit/cb886dccda18fcb8536ac47dc447d134bb89602c) the proposed approach as well, but files were not properly written into the specified directory.
