Hi Srecko
On [1] is mentioned that setting the system property
java.nio.debug=pipe
might help to get some additional information on why this is happening.
In addition I found [2] that says that the system properties
org.apache.felix.http.nio
org.apache.felix.https.nio
can be used to deactivate the use of NIO for the http and https service of
Apache Felix.
