John Yin commented on CXF-8946:
-------------------------------
I am getting OutOfMemoryException with CXF 3.6.2 and OpenJ9 (IBM Semeru
ibm-semeru-open-jre_x64_windows_17.0.9_9_openj9-0.41.0). In the dump, there
are two thousands of threads "HttpClient-xxxx-SelectorManager". Not sure
whether it is related to this issue or
https://issues.apache.org/jira/browse/CXF-8885. I do not see this issue if
using Hotspot JVM. If it is not related to this issue, I will open a new one.
Thanks!
