XOM API for Processing XML with Java

[Daniel Lowe <dl387 AT cam.ac.uk>]

The problem I am encountering is introduced somewhere between revision 
1.82 of Builder.java (this corresponds to XOM-1.1) and 1.86 (this 
corresponds to XOM-1.2b1) with my hunch being that the cause of the 
problem in the change to canonicalizeURL in 1.86.

The error is below:
C:\My Documents\workspace\xomTest\target>java -jar 
xomTest-0.0.1-SNAPSHOT-jar-with-dependencies.jar
Exception in thread "main" java.net.MalformedURLException: invalid url: 
//file:/C:/My%20Documents/workspace/xomTest/target/xomTest-0.0.1-SNAPSHOT-jar-with-dependencies.jar!/foo/foo.xml 
(java.net.MalformedURLException: no protocol: 
//file:/C:/My%20Documents/workspace/xomTest/target/xomTest-0.0.1-SNAPSHOT-jar-with-dependencies.jar)

This occurs when doing new Builder().build(u.toString()); where u is a 
URL pointing to a file within the jar that the program is running from.
The exact same code works from within my IDE, when the resource has not 
yet been placed in a jar.

If you would like to see my test code you can download it from:

To reiterate this error only occurs on Xom1.2beta and later; the code 
works fine on Xom-1.1.

Thanks for your help,

Daniel
