Last week I ported another feature from Karaf 3 to 4
When I install this feature in Karaf 4.3.6 then the feature:install command
runs into a OutOfMemoryException.
The Exception occurs in ResolverImpl of Apache Felix.
I enabled the debug logging of the logger org.apache.felix.resolver. I
found out that many time such log messages are written:

jaxb-api-2.3 comes from apache-cxf-3.4.5-features.xml
system/org/apache/cxf/karaf/apache-cxf/3.4.5/apache-cxf-3.4.5-features.xml

jaxb-api-2.2 comes from framework-4.3.6-features.xml
system/org/apache/karaf/features/framework/4.3.6/framework-4.3.6-features.xml

I need CXF for my feature.
Has some an idea how to solve this problem?
