We are using HXTT to create a managed JDBC connection pool in a Payara app server. The HXTT app is running as a windows service. The version of HXTT we are currently running is from Dec. 2019, and works well. However, we have attempted to upgrade to a newer version (2021-06-22) and we have run into a problem.
The app server (Payara) is configured to have a maximum heap size of 4Gb, and using the older version of HXTT the usual heap size while running is approx. 2Gb. When we use the new version of HXTT, the heap size used rapidly expands to the maximum of 4Gb, and within a couple of hours of running time the app server becomes unresponsive. While this is happening, the windows service is running normally, with no increase in memory or CPU usage. So it seems like there is a memory leak somewhere in the client portion of the DBF_JDBC jar of that version of HXTT.
Any help would be appreciated.
