Description Jaroslav Tulach 2002-03-28 16:42:33 UTC

I am working on issue 21676 and I have run the IDE with this patch
http://www.netbeans.org/issues/showattachment.cgi?attach_id=5081 and the
arguments described there. I have found out that following class is being
loaded into the system on startup. Please investigate why  and
prevent that to happen. Thanks.

org.netbeans.modules.url.BookmarksNode

Fixed in main trunk.

Comment 2 Jaroslav Tulach 2002-04-04 06:35:44 UTC

Ok, Libor can you tell me what was wrong, I am searching for all ways
that may initialize a module class...

CVS commit report.

Comment 4 _ lkramolis 2002-04-04 07:09:44 UTC

See attached CVS commit report. Essentially I changed .instance with
.settings.

Comment 5 Jaroslav Tulach 2002-04-04 08:56:56 UTC

I do not think that replacing .instance with .settings is the best
solution. Processing of .settings takes more time then .instance.

Please continue to use .instance, you can probably use:

<file name="BookmarkNode.instance">
  <attr name="instanceClass" stringvalue="org.openide.nodes.Node" />
  <attr name="instanceCreate"
newvalue="org.netbeans.modules.url.BookmarkNode" />
</file>

which should work the same and not load the class at startup.

Comment 6 _ lkramolis 2002-04-04 09:29:43 UTC

OK, I will revert it to .instance file.

But when you filed this bug I think you should write "'Do not load
classes on startup' bug-fixing guidelines" because I fixed this bug by
.settings files. And if you do not recommend it, you should publish
tips, how to correctly fix it. Thanks.

Used .instance files with "instanceOf" attribute name assigned.

Comment 8 _ lkramolis 2002-04-04 14:20:41 UTC

Jardo, I used your proposed solution again by .instance file. I have
extended it with instanceOf attribute name which is necessary:

<attr name="instanceOf" stringvalue="org.openide.nodes.Node,
org.openide.nodes.AbstractNode, org.openide.loaders.DataNode,
org.openide.loaders.DataFolder$FolderNode,
org.netbeans.modules.url.BookmarksNode" />

Is it right now?

Comment 9 Jaroslav Tulach 2002-04-13 14:11:27 UTC

Seems like BookmarkNode is gone. 

Other possible trick is to write 

<attr name="instanceClass" stringvalue="org.openide.nodes.Node" />

then you might skip the instanceOf attribute.

Resolved for 3.4.x or earlier, no new info since then -> closing.
