There appears to be a bug in version 1.32 of Element.java, in getText():
&lt;br&gt;it doesn't check for content==null before accessing its methods.
&lt;br&gt;This causes a
&lt;br&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; Exception in thread &quot;main&quot;
java.lang.NullPointerException:
&lt;br&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; at org.jdom.Element.getText(Element.java:420)
&lt;br&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; at org.jdom.Element.getTextTrim(Element.java:451)
&lt;p&gt;in my application. This can happen when using a schema that defines
&lt;br&gt;an element with attributes only (content=&quot;empty&quot;).
&lt;p&gt;The obvious fix is :
&lt;p&gt;if ((content != null) &amp;amp;&amp;amp; (content.size() == 1)) {
&lt;br&gt;&amp;nbsp;...
&lt;br&gt;}
&lt;br&gt;&lt;b&gt;else if (content == null)&lt;/b&gt;
&lt;br&gt;&lt;b&gt;{ // handle no content.&lt;/b&gt;
&lt;br&gt;&lt;b&gt;return null;&lt;/b&gt;
&lt;br&gt;&lt;b&gt;}&lt;/b&gt;
&lt;br&gt;&lt;b&gt;&lt;/b&gt;&amp;nbsp;
&lt;p&gt;BTW, I'm sending you this because:
&lt;br&gt;&amp;nbsp; 1. there is no (apparent) link to posting bug reports on the
jdom.org site.
&lt;br&gt;&amp;nbsp; 2. I&amp;nbsp;am not a contributor (although I'd like to be, if
I&amp;nbsp;knew how).
&lt;p&gt;thanks.
&lt;br&gt;&amp;nbsp;
