Subject class loader problem
Date Thu, 30 Apr 2015 14:08:30 GMT
Hi,

I am using Apache Karaf 2.3.4 and I am trying to install a spring-dm based
bundle but I am getting this error:

2015-04-30 17:06:11,653 ERROR org.springframework.osgi.extender:1.2.1(155)
[SpringOsgiExtenderThread-1]

I am new to OSGI and what I understand is that the spring-dm version I am
using (1.2.1) is using a different a different logger class than the one
that is installed in Karaf. Or am I wrong ?

Can you please help me to fix this ?

Thank you.
