This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Open the Junit help (Help | Help Sets | Junit Module Help and then seelct a page such as JUnit Module Settings. Attempt to Print the page. The print dialog comes up. Once the dialog is completed, cpu utilization goes to 100%. Once in this state there is no way to continue without killing the two processes (NetBeans and JUnit Module Help) which results in the loss of any file modifications which had not been saved to disk. I originally discovered this bug with 3.5RC3, then upgraded to the final release of 3.5 and duplicated it. I have been able to replicate it at will on two different computers, two different operating systems (Win XP Pro and Win 2K). The problem does not seem to depend upon the target printers (HP LJ 3100 and HP LJ 5MP). I have been able to print other random help pages without problem so feel that there is something interesting about the JUnit module help.
