Bug 206096

Summary:	The DefaultOutlineCellRenderer code checks for a System property which breaks unsigned applets.
Product:	platform	Reporter:	romeom
Component:	Outline&TreeTable	Assignee:	Martin Entlicher <mentlicher>
Status:	VERIFIED FIXED
Severity:	normal	CC:	mmirilovic
Priority:	P2
Version:	7.0.1
Hardware:	PC
OS:	Windows 7
Issue Type:	DEFECT	Exception Reporter:

Description romeom 2011-12-07 15:59:18 UTC

The DefaultOutlineCellRenderer is making a check for the System property, nb.useSwingHtmlRendering, which causes an AccessControlException from an unsigned applet.  Out application is successfully using an older version of the outline jar.  The Manifest inside says the version is:
OpenIDE-Module-Implementation-Version: 200906241340
OpenIDE-Module-Specification-Version: 1.4.1

Upon attempting to upgrade to the version of the jar packaged with Netbeans 7.0.1, the AccessControlException began happening.  It also happens with the jar from version 7.1 as well.


The following is the stacktrace from a simple unsigned applet example (the code does nothing more than instantiate the DefaultOutlineCellRenderer):

Exception in thread "thread applet-PropertyTestApplet.class-1" java.lang.ExceptionInInitializerError

It's fixed by changeset:   208605:d7a5471edf3f

I'm making this a candidate for 7.1 patch.

Just catch (SecurityException se) is added, it should not cause any problem in patch1.

Comment 5 Jiri Kovalsky 2012-02-16 14:17:25 UTC

Martine, how can I reliably reproduce the problem in 7.1? Thanks.

Comment 6 Martin Entlicher 2012-02-16 15:16:30 UTC

Well, I didn't try to reproduce the problem. romeom, could you please verify that it works fine for you now.

It's not possible to verify this inside NetBeans IDE. You'd have to take the platform/modules/org-netbeans-swing-outline.jar and create some applet application, that uses the Outline.

Comment 7 Jiri Kovalsky 2012-02-27 13:21:15 UTC

I have not encountered any such exception during my 7.1.1 testing thus marking bug as verified.
