Select tool extremely sluggish

[osm@…]

The select tool in JOSM 1561 (W_XP) is so slow that I can watch the lines beeing drawn. IIRC this was not the case in JOSM 1546 I used before.

Try JOSM run in this mode.

java -Dsun.java2d.d3d=false josm-latest.jar

I already get a number of error message when I try to start JOSM with "java josm-latest.jar" from the Command Prompt. Usually I use just "josm-latest.jar". How do I add the start option? (note this is Windows XP)

1,Open notepad
2,Write or copy command there
3,Save it without txt extension (2nd option in combo menu when save) append CMD extension.
4,Move this bath file in folder where josm-latest.jar is saved and run
5,You can see some debug msg, but you are now running josm with some parameters. You can extend your memory there. Add -Xmx1024M for example.

When I do as you wrote I get the error messages mentioned:

Exception in thread "main" java.lang.NoClassDefFoundError: josm-latest/jar
Caused by: java.lang.ClassNotFoundException: josm-latest.jar
...
Could not find the main class: josm-latest.jar. Program will exit

try

Thanks, I was able to start it now and the sluggish behaviour disappeared. What does that mean exactly? Is this still a bug in a component which can be switched off and shouldn't this option be disabled then by default?

Its problem of JAVA. You can see #2184
