R – Why would exporting an eclipse RCP product hang

eclipsercp

I am building Mac and Win versions of an RCP product using Eclipse 3.5.1. I've installed the RCP delta pack and everything looks great. However, when I go to export, the progress bar gets stuck at "Publishing Metadata" (about 20% through the export process). It never makes any progress after that. Further, cancelling has no effect at all. I have to kill Eclipse to end it.

The workspace .metadata/.log file has no warnings at all.

Any ideas?

Best Solution

The answer to this (for me) seems to be to make a new .product file using the new version of Eclipse. As soon as I did this all was well. Thanks to anyone who gave it some thought.

Per the commenter's great suggestion I went to bugs.eclipse.org and found this bug which is the source of my hang
