Failure output (captured from console output)

10:58:40  ACTION: testng -- Error. Program `/home/jenkins/workspace/Test_openjdk11_j9_sanity.openjdk_aarch64_linux/openjdkbinary/j2sdk-image/jdk-11.0.7+9/bin/../bin/java' timed out (timeout set to 960000ms, elapsed time including timeout handling was 962206ms).

This test is known to intermittently timeout on aarch64. We will add this test to the exclude list and revisit later.

The 0.21.0 m1 build takes 785 seconds on cent7-aarch64-1 to run this test. Timeout value is 960 seconds.

We should find out how long this test takes to run on x86 for relative comparison. If there is a wide difference then there might be something pathologically wrong with AArch64 (e.g., methods are being interpreted) rather than just device slowness.

@0xdaryl It seems java/net tests are not executed in sanity.openjdk now, and I don't have numbers. https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_sanity.openjdk_x86-64_linux/256/testReport/ https://ci.adoptopenjdk.net/job/Test_openjdk11_j9_sanity.openjdk_ppc64le_linux/260/testReport/

My local AArch64 build with recompilation runs this test in 420 seconds on cent7-aarch64-1, 47% shorter than 785 seconds without recompilation.

I believe this issue can be closed. The test has been enabled since June last year.
