Win7 Java version for Arduino IDE 1.8.16

I'm running a virtual machine with Win7 and Java version 8, update 181 (build 1.8.0_181-b13) and Arduino IDE 1.8.19. It occasionally hangs and becomes unresponsive until I force a shutdown or reboot and get a windows memory exception error.

Is there a preferred version of Java for this OS and IDE?

IDE 1.x comes with its own JRE and as far as I know (but not sure) that is used. If you have Oracle Java or some other Java installed, you can uninstall it and the IDE should still work.

I have had plenty of systems without Java installed where the IDE happily worked (obviously using the included JRE).

Thanks. I'll have to debug more and find the root cause of the problem then.
