---------------------------------

    Attachment: synapse.zip

Hi Asankha,

I send the log file directly, because I don't want to disclose our service 
names and installation paths.

Thank you.

Mit freundlichen Grüßen

--------------------------------------------

I've tried both with Synapse 1.2 original JARs and a private maintenance 
branch, and I cannot re-create this exception. Could you attach the very 
fist log file where this error will be reported after the startup? If the 
log file contains sensitive information, you may zip it and send it to me 
directly

HttpCore 4.1-alpha1
occurs that shows a NPE with the following stack trace.

unstable: IOReactor encountered a runtime exception : null
