Error occurred during initialization of VM
Option AOTCache cannot be used at the same time with -Xshare:on, -Xshare:auto, -Xshare:off, -Xshare:dump, DumpLoadedClassList, SharedClassListFile, or SharedArchiveFile

We should either skip the test with @requires vm.flagless, or get rid of -Xshare:off for the alt. substitutability. The latter is probably the better route as heap dumping is now integrated.
