Hi, This might be caused by "busy loop hangs" in the Java "PiscesRenderingEngine", I had a similar issue in poi-benchmark <https://github.com/centic9/poi-benchmark> , I solved it by switching to the "MarlinRenderingEngine" as described in the second "Note" at https://poi.apache.org/components/slideshow/ppt-wmf-emf-renderer.html
I download the additional jar at https://github.com/centic9/poi-benchmark/blob/master/runBenchmark.sh#L13 and patch the build.gradle file at https://github.com/centic9/poi-benchmark/blob/master/src/jmh/java/org/apache/poi/benchmark/suite/BaseBenchmark.java#L144 Not sure what actually triggers the endless-loop, maybe a specific patchlevel of the JDK or maybe some timing needs to fall in place. It is really annoying that the JDK 8 does not seem to get a fix for this any more. We could try to make this a "permanent" in our tests, but it would add even more complexity to the build. Another option that I am considering is to discontinue support for JDK 8 and only support JDK 11+ to be able to remove quite some build-logic. Regards... Dominik.
