FULL PRODUCT VERSION :
1.6.0_02

ADDITIONAL OS VERSION INFORMATION :
Seen on different windows version, one of them being:
Microsoft Windows 2000 [versie 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
See the code below. It is a fragment that is used to dynamically build a menu bar depending on the contents of an XML file. The code runs fine when using JRE 1.6.0_01 but gives a javax.xml.stream.XMLStreamException when running in JRE 1.6.0_02. The exception occurs in the line where xer.hasNext() is called (see attached code). The details of the exception are: " ParseError at [row,col]:[1,39]: Message: expected start or end tag". The location mentioned is the character just after the end of the "<?xml version='1.0' encoding='UTF-8'?>" declaration in our XML file. The XML file has a rather simple structure; we do not use any DTD or XML schema.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Try the attached code on a file like this:

<?xml version='1.0' encoding='UTF-8'?>
<menubar>
<menu>
<id>file</id>
<item>
<id>exit</id>
<method>doExit 0</method>
<type>all</type>
</item>
</menu>
<menu>
<id>edit</id>
<item>
<id>prefs</id>
<method>showPrefsWindow 0</method>
<type>all</type>
</item>
</menu>
</menubar>




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The file is parsed.
ACTUAL -
Exception occurs.

---------- BEGIN SOURCE ----------
        XMLInputFactory xif = XMLInputFactoryImpl.newInstance();

CUSTOMER SUBMITTED WORKAROUND :
Use older JRE (1.6.0_01). This means automatic updates have to be disabled for all our users, which is not desireable.

Release Regression From : 6u1
The above release value was the last known release where this
bug was not reproducible. Since then there has been a regression.
