           Summary: Correctly propagate exception information from NPAPI
                    callbacks
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: cwzwarich at uwaterloo.ca


It came up when fixing bug 19907 that we don't propagate any exception
information in an NPAPI callback. The NPAPI reference suggests that we should
return false, at least in some cases:

http://developer.mozilla.org/en/docs/Gecko_Plugin_API_Reference

Some compatibility testing will be required, because the NPAPI documentation
isn't very specific.
