'illegal unicode escape' error in RegularExpression.java with SunJRE 1.4.2

[Michael Davey]

Hello,

Sun's JRE version 1.4.2 fails to compile Xerces2-J, reporting an 
'illegal unicode escape' error in 
java/build/src/org/apache/xerces/impl/xpath/regex/RegularExpression.java

Sun currently thinks that this is caused by a regression in the JRE, 
between versions 1.4.1_02 and 1.4.2-beta.  This is Sun BugID #4863451, 
if you are a registered Java developer, you can read the latest status 
on  Java BugParade 
<http://developer.java.sun.com/developer/bugParade/bugs/4863451.html>.

Workarounds:
 *  Use a Sun JRE with version number below 1.4.1_02
 *  Use another vendor's JRE
 *  Manually edit the source, replacing "\u005cu" with "\u005c u"
I have five questions:

 *  Do at least some of the regular Xerces2-J developers know about this?
 *  If so, Is the information above correct, to the best of your knowledge?
 *  Is there anything else I should know about this?
 *  Shall I open and immediately close a bug against Xerces-J on this 
issue (as "not-a-bug", with reference to Sun's bug number)
 *  Shall I submit a patch for the website FAQ section and if so, for 
the "common problems" or the "build and compile" section?
