[ jEdit-devel ] xml-commons-resolver.jar causes weird problems with the XML/sidekick plugin

[dAniel h. <ge...@th...>]

Hello,

yesterday I've noticed a NPE when I've tried to use sidekick-complete
in a CSS file. I've debugged this using Eclipse and found that
cssproperties was null, although it should have been set in during
initialization.

Somehow cssSideKickCompletion.readCompletionConfig did not finish, nor
threw an error. At some point there was a java.lang.NoSuchMethodError
in org.apache.xerces.util.XMLCatalogResolver.init.

The activity log showed only
[debug] CssSideKickCompletion: Parsing configuration file:
jeditresource:/XML.jar!/xml/completion/css-complete.xml
but missed
[debug] CssSideKickCompletion: Parsing done, found 95 css properties
and 9 css units
or any error.

I could not really debug this using Eclipse either (and am no Java
expert for sure), but the solution then was to remove
~/.jedit/jars/xml-commons-resolver.jar!
I don't know where the file is from, maybe I had copied it there
manually while trying to build the XML plugin some years ago - I'm not
sure at all.

The file is dated 2004-06-27 and the manifest says 1.2.2 (Sun
Microsystems Inc.).

Just in case this is an old library of some plugin, we should make
sure that it gets removed.

Is there any way to detect such library messups (and report it to the
user somehow)?
At least it seems like there was no indication in the activity log
(apart from the NPE when calling sidekick-complete).
