OSM-Data upload does not work (because of API change?)

Hi, I´m working on JOSM 1526 and since a few days I have problems with the data upload: There is no error-message but the data is not on the osm-server afterwards. During the upload there is a new message to give a comment about the changes made and afterwards it seems to send data to the server. Another odd thing is, that recently I always get an error-message on JOSM start up (memory and strange things may happen…) although I extended the memory to 512MB… maybe there´s a relation between these things?
Thanks for the help.

Its recommended that you use at least JOSM version 1529, as earlier versions don’t work properly with the new API (according to this page: http://wiki.openstreetmap.org/wiki/OSM_Protocol_Version_0.6/Information ).

I think you might as well get the latest more or less stable version (1566) as there’s been a few other improvements since then.

I will check this… Thanks.

It seems to work… upload is on the osm-server!
