[Squirrel-sql-develop] NullPointerExceptions and squirrel syntax plugin

[Joseph B. <jb...@ww...>]

Here's some more information regarding my problem with the syntax 
highlighting plugin and squirrel.

The prefs.xml file I have has an empty <fontInfo> element under 
SessionProperties.

<sessionProperties
  Class=
"net.sourceforge.squirrel_sql.client.session.properties.SessionProperties"
 >

  --snipped--

  <fontInfo/>


If I replace it with the default fontInfo section that is created for a 
'new' squirrel user (one without a prefs.xml file present), my problem 
goes away :


    <fontInfo Class="net.sourceforge.squirrel_sql.fw.gui.FontInfo">
            <family>Monospaced</family>
            <isBold>false</isBold>
            <isItalic>false</isItalic>
            <size>12</size>
    </fontInfo>

I've looked at the source, and see that a new SessionProperties object 
gets a default (non-null) FontInfo object created for it.  I believe my 
having an empty <fontInfo/> tag in my prefs.xml cause the XMLBeanReader 
to assign assign call sessionProperties.setFontInfo(null).

I'm not sure how to best adjust the code to deal with the problem, but I 
believe you can re-produce my problem by editing your prefs.xml and 
change the <fontInfo> section into an empty tag :

   <fontInfo/>


Hope all of this helps.
