Description

I discovered that a QNameSet created from QNameSet.forArray(QName[]) cannot be used as an argument to QNameSet.union(qnameSetFromArray). The set-based factory method

QNameSet.forSets(null, Collections.EMPTY_SET, Collections.EMPTY_SET, qnames);

works fine. I am currently using xmlbeans 2.0 but it looks to me by examining the code that the problem is still present in trunk. I believe that the problem is that in
public static QNameSet forArray(QName[] includedQNames)

{ if (includedQNames == null) throw new IllegalArgumentException("includedQNames cannot be null"); return new QNameSet(null, new HashSet(), null, new HashSet(Arrays.asList(includedQNames))); }

the third set is null rather than empty.
