Re: Activation related stack traces after upgrading to 4.2.15

[Gregor Eichelberger]

Hi Łukasz,

if you replace the 
org.apache.servicemix.specs.activation-api-1.2.1-1.2.1_3.jar
from the distribution folder lib/jdk9plus/ with the version 
org.apache.servicemix.specs.activation-api-1.1-2.9.0.jar
the NPE is gone, and the Content-Type "multipart/form-data" is working 
as expected.

Best,
Gregor

Hey Greg,
Looking at the stack trace it originates from an system dependency we
have and not Karaf itself. Are you able to reproduce issue without Karaf
(ie. running stock CXF), or it happens only when you deploy your service
within our runtime?

BTW would your organization be interested in providing a story for
https://karaf.apache.org/stories.html ?

Best,
Łukasz
