poor performance with relation editor dialog

[elyk]

After opening the relation editor dialog a few times, performance takes a nosedive. In particular, performance seems fine until a certain point whereafter it takes a long time to draw any dialog box on the screen. Opening the relation editor dialog a few times triggers the behavior.

I've tried running top to investigate exactly when this problem happens. Opening the relation editor dialog will cause the virtual memory size (VIRT column) to increase by about 4m or 5m each time I open it. If I run java -Xmx768m -Dsun.java2d.opengl=true -jar ./josm-latest.jar then the performance tanks when the VIRT column reaches about 1024m.

I've tried changing the -Xmx option to 512m and 1024m. The problem happens when the VIRT column gets to about 768m and 1280m, respectively. In all cases, that's about 256m above the value I give for -Xmx.

What can be done about this? Can the relation dialog be improved to not gobble up 4 or 5 megabytes of virtual memory every time it is opened?

When you are talking about "Opening the relation editor dialog a few times" do you mean open and cancel/abort or opening and save the relation? Because if you save the relation the memory loss may be caused by the undo operation that saves the previous relation version.

Besides that it does not hurt to add the following line to the RelationEditor constructor:

setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

I don't know if it matters or not, but I'm using Slackware 12.1.

I mean open and cancel.
