Heap memory increasing without any reason

[AlexisDrogoul]

Describe the bug
After launching GAMA, in the lack of any specific action, the used heap memory steadily increases, reaching almost 1G after 10 min. Forcing a garbage collect makes it go back to the initial level (so there are no leaks).

Expected behavior
That no memory is being used silently like this.

Desktop (please complete the following information):

• OS: macOS Sonoma
• PC Model: MBP M3 Max
• GAMA version: git
• Java version: 21

After a careful analysis with YourKit, it turns out that the guilty process is the call to PollingMonitor.run() by Eclipse to periodically refresh the workspace. I had never noticed that before, but it seems harmless at first sight. To "fix" it, one can turn off the preference "Refresh using native hooks or polling" in the "Advanced..." section of the prefs, under General>Workspace.

Although not completely satisfying, it is a workaround.

The issue is still here on macOS Sequoia + Eclipse 2024-09, but much lighter : reaching 1G of used (and reclaimable) memory takes now 2-3 hours... So I close this issue from now on.
