I would put a D in front of GC. The issue relates to the DGC in RMI, and it is possible that a race condition could occur in the test. If you add -Dsun.rmi.dgc.logLevel=VERBOSE as follows and execute the test this should generate some informative trace @run testng/othervm -Dsun.rmi.dgc.logLevel=VERBOSE FilterUROTest generates trace as follows: Feb 09, 2023 9:50:57 AM sun.rmi.transport.Target pinImpl FINER: MainThread: strongRef = sun.rmi.transport.DGCImpl@7cbf0dfe Feb 09, 2023 9:50:57 AM sun.rmi.transport.DGCImpl$2 run FINER: MainThread: add object [0:0:0, 2] Feb 09, 2023 9:50:57 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7fff, 5531192820167141595] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ffd, 8746623791996069441] Feb 09, 2023 9:50:58 AM sun.rmi.transport.ObjectTable$Reaper run ************* REAPER RUNNING FINER: RMI Reaper: remove object [62fd29ac:1863595d6b8:-7fff, 5531192820167141595] ***** obj removed Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ffb, 1056299151672018720] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ff9, 8876407693706706001] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ff7, -7965896295360386187] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ff5, -7624739283438349379] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ff3, 7826842570026353870] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7ff1, 2393465261706369534] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7fef, -1516555594713694850] Feb 09, 2023 9:50:58 AM sun.rmi.transport.Transport exportObject FINER: MainThread: add object [62fd29ac:1863595d6b8:-7fed, 2782915653950164382] STATUS:Passed. ------------- PR: https://git.openjdk.org/jdk/pull/12399
