When read/modify/save kb project stored in xml file, class IhcludeModel correctly adds new <alias> entries, but duplicates existing entries, reverting data in copies. For example, for entry
<alias path="/weld1.1/src/META-INF/beans.xml" value="%8"/>
it creates new entry
<alias path="%8" value="/weld1.1/src/META-INF/beans.xml"/>
In this way, section <aliases> contains twice as much entries as it should. This corruption does not affect functionality, but creates performance load.
