Description

Running TestMobStoreScanner, looks like it may need to go on a diet. The test case testGetMassive will reliably OOME for me. It might be because I am using an aarch64 Java 8 JVM and surefire.Xmx as currently defined in pom.xml at 2200m is not quite enough.

2022-02-18T17:04:04,886 ERROR [RS:0;buildbox:45315] util.OOMEChecker(40): Run out of memory; RSRpcServices will abort itself immediate
ly
java.lang.OutOfMemoryError: Java heap space

Where the OOME is thrown is usually not germane so the rest of the stacktrace is not included.
A repeatable failure for me.
