Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Dan Smith (dlsmith) Assigned to: Nobody/Anonymous (nobody) Summary: Open causes NullPointerException Initial Comment: I'm able to intermittently, but fairly reliably, produce this NullPointerException by opening a certain folder or files within the folder (for future reference, it's location is Code/misc/astgen/nodes, although I noticed this with other sets of files as well). It seems to have more to do with the number of files (usually 30+) being opened than the names or contents of those files, but as it is intermittent, it's hard to perform reliable experiments.
