rev 3922 (local build) runs out of memory when trying to upload to osm

[hjart]

On my system 3922 behaves fine until I hit 'Upload to OSM' after which time cpu and memory use shoots up wildly and after a short while gives me the attached msg. No attempt to upload succeeds.

The text below is from the console:

java.lang.OutOfMemoryError: GC overhead limit exceeded

Out of memory

[stoecker]

How much memory do you give Java? The Java defaults are much too small.

[Zverikk]

Not too small, I start josm with "java -jar josm-latest.jar" all the time, and only experience OOM error after very intensive use of Bing imagery (#5971).

[bastiK]

confirmed, this is probably related to [3922]

[hjart]

I tried giving it 2500M (out of my 4000), but to no avail. JOSM ate all of it and made the whole system unresponsive. Had to kill it. And I never had to give Java extra memory before (and I've actually used JOSM quite a lot over the last year ... and I have to thank you for all the work you've put in it).

[*Martin*]

Affects me too even with -Xmx1240m. It is probably caused by validator. In r3915 it worked.

[bastiK]

In [3923/josm]:

fixed #6007 - runs out of memory on validater cross ways check (TODO: initializeGridDetail hack needs proper implementation)
