The following test failed in the JDK20 CI:

sun/management/jmxremote/bootstrap/RmiSslNoKeyStoreTest.java

Here's a snippet from the log file:

<snip>

result: Error. Agent communication error: java.io.EOFException; check console log for any additional details

There's no indication of an error except for the above 
" Agent communication error: java.io.EOFException". 
No hs_err_pid file, no indication of a problem with the test 
execution, no core file. 

This same failure happened on a linux-aarch64-open and
a linux-aarch64-debug test machine in jdk-20+14-900-tier6.

We recently had the same failure mode with a different test:

JDK-8293335 sun/management/jmxremote/bootstrap/RmiBootstrapTest.java#id1failed with "Agent communication error: java.io.EOFException"

Fix request [17u] I backport this for parity with 17.0.11-oracle. No risk, only a test change. Omitted change to PRoblemList, rest is clean. Tests pass. SAP nightly testing passed.

Test failure reproduces frequently for me. With the othervm jtreg tag it stopped failing (batches of 20 test runs on each platform). diff --git a/test/jdk/sun/management/jmxremote/bootstrap/RmiSslNoKeyStoreTest.java b/test/jdk/sun/management/jmxremote/bootstrap/RmiSslNoKeyStoreTest.java index 41b303399cc..78ccaa86c5f 100644 --- a/test/jdk/sun/management/jmxremote/bootstrap/RmiSslNoKeyStoreTest.java +++ b/test/jdk/sun/management/jmxremote/bootstrap/RmiSslNoKeyStoreTest.java @@ -48,7 +48,7 @@ import javax.management.remote.JMXConnectorServer; * * @library /test/lib * - * @run main/timeout=300 RmiSslNoKeyStoreTest ._ssltest..in + * @run main/othervm/timeout=300 RmiSslNoKeyStoreTest ._ssltest..in * / /*
