A DESCRIPTION OF THE PROBLEM :
Using a xsd schema with imports:
<xs:import namespace="http://www.w3.org/1998/Math/MathML"
schemaLocation="../mathML/mathml2.xsd" />

works with the webstart classloader and with the Java classloader, when the path does not contain umlauts.

java -Duser.home="./ingrid.prass/" Test

does not work, when the path contains umlauts:

java -Duser.home="./ingrid.praß/" Test

Inflate the http://prp.heiko-wiesner.de/classloaderProblem.zip and run the Test with the 2 upper commands.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Message: Sucessfully created schema in the console
ACTUAL -
