I have an RCP application that hangs when I open a DirectoryDialog on Java 6 only (no problem on Java 5) with both a Sun or IBM VM.

After my command is executed it runs the following code:

DirectoryDialog dialog = new DirectoryDialog(window.getShell());
dialog.open();

After the user selects Ok the dialog goes away and the UIThread becomes unresponsive.

This occurs in both 3.4.2 and 3.6.1

Here is the stack trace of the main Thread when it happens:

This sounds like https://bugs.eclipse.org/bugs/show_bug.cgi?id=312137 . He
didn't mention jre5 vs jre6, and you didn't mention leaving the input field
blank, but I'm guessing it's the same problem (?).
