I had updated my Version 3.4 to 4.0 like the Documentation. I do everything for java and strong java.
When I now start my Vibe, everything is fine. But after some time the ssl connection is down, after restart everything fine.
I found this in catalina.out:
WARNING: 'org.apache.xerces.jaxp.SAXParserImpl: Property 'http://javax.xml.XMLConstants/property/accessExternalDTD' is not recognized.'

Im using
jdk-8u45-linux-x64 and jce_policy-8 like Documentation.

Vibe is running on a SLES 11 SP3 fullpatched
