HelpFlagsTest.java appears to fail on Windows 32bit (and not Windows 64bit), with the following error:

23:47:39 STDERR:
23:47:39 java.lang.AssertionError: HelpFlagsTest failed:

Since this appears to be a straightforward test setup/config issue with low priority, I'm raising this bug to register the issue's existence until such time as I (or anyone else with free time) get around to creating a fix.

Note: Looks to be as simple as adding jaccessinspector-32 and jaccesswalker-32 to TOOLS_NOT_TO_TEST at the top of HelpFlagsTest.java, as the non-32bit versions are already there.

Issue seen on JDK11 and JDK16, and the test doesn't appear to exist on JDK8.
