@TobiAjila I see failures in cmdLineTester_criu_nonPortableRestore tests all the time for the past few weeks, are we working to fix that?

Some of them are #18384

tajila · 2023-11-08T14:11:33Z

Some of them are #18384

Yes @JasonFengJ9 Is looking into it

tajila · 2023-11-08T14:14:05Z

@singh264 Can you please take a look at this. You can generate a system core when the JVMRestoreException is triggered to determine what is causing the blocking operation.

singh264 · 2023-11-08T20:27:25Z

@tajila I generated a system core file when JVMRestoreException is triggered during the test failure. In addition to the options in dumpOptionsTestRequireDynamic, I observe the error for the options in TraceOptionsTest2 and TraceOptionsTest3.

singh264 · 2023-11-10T21:25:31Z

@singh264 Can you please take a look at this. You can generate a system core when the JVMRestoreException is triggered to determine what is causing the blocking operation.

The blocking operation seems to occur during the CRIUSupport.clearInetAddressCache() post restore hook when MethodHandleResolver.resolveInvokeDynamic(..) is called before CRIU single thread mode is disabled in Java_org_eclipse_openj9_criu_CRIUSupport_checkpointJVMImpl(..).

During the test failure, the code path taken from MethodHandleResolver.resolveInvokeDynamic leads to PhantomCleanable.insert() that includes a synchronized block and the monitorenter bytecode. It seems like the code path taken when resolveInvokeDynamic is called is not always the same since the test fails intermittently.

@tajila How could a blocking operation be supported for CRIU single thread mode during the CRIUSupport.clearInetAddressCache() post restore hook when MethodHandleResolver.resolveInvokeDynamic(..) is called before CRIU single thread mode is disabled in Java_org_eclipse_openj9_criu_CRIUSupport_checkpointJVMImpl(..)?

@tajila How could a blocking operation be supported for CRIU single thread mode during the CRIUSupport.clearInetAddressCache()

We dont support blockign operations in single thread mode. The way to address this is to determine which thread owns the contended resource, then make sure that thread is not halted while holding the resource with @NotCheckpointSafe annotation which is applied to methods.

pshipton · 2023-11-15T12:40:33Z

Although I put this into the 0.43 milestone, we also get "Blocking operation is not allowed in CRIU single thread mode." failures in jdk21 builds.
