Bug 31576 2.1M5 NullPointerException in ClassPathDetector.detectOutputFolder
Reported: 2003-02-11 13:52:38 | Status: resolved fixed

I'm attempting to create a new Java Project and point it to a directory in my ClearCase directory. It appears that in an attempt to discover source directories and libraries, a NullPointerException is being thrown. This is in version 2.1 M5. The relevant information from the log is: !SESSION Feb 11, 2003 12:35:23.406 --------------------------------------------- java.version=1.4.1_01 java.vendor=Sun Microsystems Inc.
