Out of memory completely stalls program instead of displaying a message

[skyper]

What steps will reproduce the problem?

1. Start JOSM with little memory
2. Load several times two different versions of locally, complete defaultpresets.xml
3. Run out of memory for an unknown reason as it worked a few times while loading the local files

What is the expected result?

A nice message about "Out of memory" in a new dialog and JOSM continues to work.

What happens instead?

No user information and JOSM stalls completely.

Please provide any additional information below. Attach a screenshot if possible.

Think, this happened to me once when loading a huge OSM data file and adding an imagery layer, too.
I have not seen the dialog about "Out of memory" for a while now, so something is broken, here.
