perry he commented on ABDERA-434:
---------------------------------

This solution works, thanks Andreas! 

however, there is one issue when to use "fom-impl-1.2.16.jar", do you have idea to make it
work? Thanks in advance!
- Seems Entry can set category with schema as "null" but is unable to get category with schema
"null": 
when to call entry.addCategory(entry.addCategory(null, "a", "a")), it can add a new category
into (org.apache.abdera.model.Entry) entry, and the category exists in the entry like below:
   <entry xmlns="http://www.w3.org/2005/Atom" xmlns:thr="http://purl.org/syndication/thread/1.0"
xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">
      <category term="a" label="a"></category>
   </entry>
But nothing to return when to call entry.getCategories(null), I assume it would return a category
like "<category term="a" label="a"></category>".
- This issue does NOT exist when to use Abdera 1.1.3 with abdera-parser-1.1.3.jar, neither
to use Abdera 0.4.0. Same code can get category "a" with schema "null".

> We are going to replace Abdera 0.4.0 with 1.1.3, there is an exception thrown out in
code below, is this a known issue, a bug or something wrong to invoke the method? The same
code works well with Abdera 0.4.0 and axiom-api-1.2.5.jar.
> - code to call:
> Line 1: Content contentElement = atomEntry.getContentElement();
> Line 2: if (contentElement != null && contentElement.getSrc() == null)
> Line 3:            entryText = contentElement.getValue();
> Line 4: String updatedContent = MentionsUtil.checkMentions(entryText, id);
> Line 5: contentElement.setValue(updatedContent);
> - exception:
> java.util.ConcurrentModificationException: The current node has been removed using a
method other than Iterator#remove()
> 	at org.apache.axiom.om.impl.traverse.OMAbstractIterator.hasNext(OMAbstractIterator.java:67)
> 	at org.apache.abdera.parser.stax.FOMElement._removeAllChildren(FOMElement.java:559)
> 	at org.apache.abdera.parser.stax.FOMContent.setValue(FOMContent.java:255)
> 	at ...
> - runtime values when to throw exception:
>  a) contentElement in Line1: 
> {noformat}
> <content xmlns="http://www.w3.org/2005/Atom" type="html">&lt;?xml version="1.0"
encoding="UTF-8"?&gt;&lt;div&gt;testSaveAppDataDraftToMedia1&lt;/div&gt;</content>
> {noformat}
>  b) updatedContent in Line4:
> {noformat}
> <?xml version="1.0" encoding="UTF-8"?><div>testSaveAppDataDraftToMedia1</div>
> {noformat}
> - our code depends on other jars involved:
> abdera-parser-1.1.3.jar
> axiom-api-1.2.14.jar
> downloaded from https://abdera.apache.org/
