[news.eclipse.technology.aperi] Problem to run Aperi 0.4.1

[JHNKRAUS@xxxxxxxxxx (Johannes Kraus)]

Hello Aperians,

I have a few problems to get Aperi to run. I run Aperi on Windows XP SP2 
and have downloaded version 0.4.1. After the installation (which I have 
done like the description on 
http://www.eclipse.org/aperi/documentation/r4/install.php with derby as 
database repository), I get an error, when I run the aperi.bat (the error 
occurred in the agent\agent.bat):
Exception in thread "SANAgentHostQuery" java.lang.LinkageError: loader 
constraint violation: loader (instance of 
org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) previously 
initiated loading for a different type with name

When I start the gui/AperiRcpGui.exe there pops up a ?Progress 
Information? window with the message ?Getting services for localhost...?, 
after that an Error Message appears: 

Error --
Server: localhost         Status: 24
14.09:33:16 SRV0024E: The requested service provider has been shutdown.


When I click the ?OK? button, Aperi crashed. 

Any ideas?

Kind regards
Johannes
