If you want the SA tests to be reliable with something like InitialRAMPercentage=0, probably all of the tests should be updated. However, personally I don't think this type of fix should be necessary unless you feel testing in the manner is something we want to support. There are plenty of tests that start failing when non-standard command line options are used. ------------- PR Comment: https://git.openjdk.org/jdk/pull/28637#issuecomment-3607775022
