Hi, I made some tests with superversion and run into the following errors - <html><body bgcolor=#FFFFFF>java.lang.NullPointerException <br> at

<br></body></html> I have no idea about the meaning of this messages. I have no experience with java. I can reproduce this error messages when trying to open a project from a remote server. Opening the same project on the server is no problem. In client log windows shows (time stampes cut out) - at java.awt.EventDispatchThread.pumpOneEventForHierachy(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) The client is a slow 200MHz machine and it takes more than a minute till the error pops up. Closing the error box takes several minutes. The window title bar says [Synchronizing...] all the time. After this the cpu load drops from 100% to the usual 6%, but the java session is unusable - means do not respond to mouse clicks. I have to kill the process. Is my client machine to slow and run into a timeout here? Or could you explain what this errors mean? Superversion 2.0 Beta 8b Java 1.4.2_05 from Innotek running on eComStation1.1 (OS/2 Warp 4.52) Many thanks, Andreas |
