The diagnostic heap dump endpoint /heapDump/ cannot be used to download heap dumps anymore because it does not meet the requirements of openjdk/jdk@fb87831: The temp file has a hprof suffix, not .hprof, so does not pass this check.
This was introduced in:
https://www.oracle.com/java/technologies/javase/7u151-relnotes.html
https://www.oracle.com/java/technologies/javase/8u141-relnotes.html
https://www.oracle.com/java/technologies/javase/9-relnotes.html
A workaround would be to set the system property jdk.management.heapdump.allowAnyFileSuffix, which can be done while Jenkins is running, via the script console.
