Live platform FXDD ver. 2.32.4 JForex API ver. 2.9.6.2
I don't have a reproducible scenario for this, but have had problems with JForex platform not using the latest .jfx compiled versions for Local Run.
I deleted the on-disk .jfx file, then compiled again, but new version was not run. On full platform restart the new .jfx version was being run.
I assume the run information is held in an in-memory cache of some kind, and that cache may not be releasing older versions under certain circumstances.
If any changes have been made recently in the in-memory jfx object cache, you might want to review them.

I'll withdraw this, as there is a possibility that Thread issues could have resulted in residual code not being released on Strategy close.
I am aware, and others should also be aware, that they MUST release any created Thread resources, as well as any Swing GUI components which may have been created by the Strategy instance, within the onStop() of the Strategy module.
Failure to do this can result in unexpected behavior.
