Maybe walk the chain of > parent directories until you find the vm.properties file? Actually my PR may not cover all VM properties. VMProps is just for computing the "extra" properties: requires.extraPropDefns = ../jtreg-ext/requires/VMProps.java But jtreg also computes "built-in" properties like `jdk.version.major`, `os.simpleArch`, etc: https://openjdk.org/jtreg/tag-spec.html#requires_names So I think the best solution may be for jtreg to save the properties to a location of its choice, and pass this location to the test cases with a property like `test.vm.properties.file`. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24071#issuecomment-2728610838
