8273803: Zero: Handle "zero" variant in #5527


Copy link

@shipilev shipilev commented Sep 15, 2021

This currently manifests if you run Zero with compiler/codecache/cli tests (part of tier1):

$ CONF=linux-x86_64-zero-fastdebug make exploded-test TEST=compiler/codecache/cli/

java.lang.RuntimeException: Unknown VM mode.
at jdk.test.lib.cli.CommandLineOptionTest.getVMTypeOption(
at jdk.test.lib.cli.CommandLineOptionTest.verifyOptionValueForSameVM(
at compiler.codecache.cli.common.CodeCacheCLITestBase.runTestCases(
at compiler.codecache.cli.codeheapsize.TestCodeHeapSizeOptions.main(

at java.base/

While these tests are compiler tests, and they should arguably never run with Zero, the problem is in shared code, which can be used in future by other non-compiler tests.

Additional testing:

  • Affected compiler tests now "properly" fail with "no compilers" errors


  • Change must not contain extraneous whitespace
  • Commit message must refer to an issue
  • Change must be properly reviewed


  • JDK-8273803: Zero: Handle "zero" variant in
