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/ STDERR: java.lang.RuntimeException: Unknown VM mode. at jdk.test.lib.cli.CommandLineOptionTest.getVMTypeOption(CommandLineOptionTest.java:504) at jdk.test.lib.cli.CommandLineOptionTest.verifyOptionValueForSameVM(CommandLineOptionTest.java:397) at compiler.codecache.cli.codeheapsize.GenericCodeHeapSizeRunner.run(GenericCodeHeapSizeRunner.java:42) at compiler.codecache.cli.common.CodeCacheCLITestCase.run(CodeCacheCLITestCase.java:62) at compiler.codecache.cli.common.CodeCacheCLITestBase.runTestCases(CodeCacheCLITestBase.java:58) at compiler.codecache.cli.codeheapsize.TestCodeHeapSizeOptions.main(TestCodeHeapSizeOptions.java:86) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at com.sun.javatest.regtest.agent.MainActionHelper$AgentVMRunnable.run(MainActionHelper.java:312) at java.base/java.lang.Thread.run(Thread.java:833) 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: - [x] Affected compiler tests now "properly" fail with "no compilers" errors ------------- Commit messages: - Fix Changes: https://git.openjdk.java.net/jdk/pull/5527/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5527&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8273803 Stats: 2 lines in 1 file changed: 2 ins; 0 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/5527.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5527/head:pull/5527 PR: https://git.openjdk.java.net/jdk/pull/5527
