You might want to update your copy of Java as you're seriously out of date and then see if this happens again. The most current version is 1.7.05, and the last branch in 1.6 was 1.6.33.

thanks for your reply, after java update josm works fine

[rickmastfan67]

Good to hear that. I'll mark this as "invalid" then. ;)
