[Bug xml/32539] New: gnu.xml.stream.XMLParser: hasNext() assumes next() to follow immediately

[kwolf at suse dot de]

The implementation of gnu.xml.stream.XMLParser.hasNext() seems to assume that
it is immediately followed by next(). This may lead to wrong results of some
other functions called after hasNext() but before next().

I expected the following code to produce the same output twice, each line
starting with "x = x" (event and reader.getEventType() should be the same), as
it does in Sun's implementation. In Classpath implementation the second line
prints "x = y" where x in general is different from y (and y is the type of the
following event).

int event = reader.getEventType();
System.out.println(event + "=" + reader.getEventType() + "; hasNext = " +
reader.hasNext());
System.out.println(event + "=" + reader.getEventType() + "; hasNext = " +
reader.hasNext());
