Overwritten by Boot Delegation

When using AEM v5.6.1 we created a number of OSGi bundles that 'wrap' 3rd party libraries. These installed successfully with no problems. Here's what one example looks like in the bundles console :-

Exported Packages    com.google.code.facebookapi,version=3.0.4 com.google.code.facebookapi.apt,version=3.0.4 com.google.code.facebookapi.schema,version=3.0.4 com.sun.xml.fastinfoset,version=1.2.13 com.sun.xml.fastinfoset.algorithm,version=1.2.13 com.sun.xml.fastinfoset.alphabet,version=1.2.13 com.sun.xml.fastinfoset.dom,version=1.2.13 com.sun.xml.fastinfoset.org.apache.xerces.util,version=1.2.13 com.sun.xml.fastinfoset.resources,version=1.2.13 com.sun.xml.fastinfoset.sax,version=1.2.13 com.sun.xml.fastinfoset.stax,version=1.2.13 com.sun.xml.fastinfoset.stax.events,version=1.2.13 com.sun.xml.fastinfoset.stax.factory,version=1.2.13 com.sun.xml.fastinfoset.stax.util,version=1.2.13 com.sun.xml.fastinfoset.tools,version=1.2.13 com.sun.xml.fastinfoset.util,version=1.2.13 com.sun.xml.fastinfoset.vocab,version=1.2.13 ...

We have recently upgraded to AEM v6 and now when I import these bundles, for any packages from 'com.sun.*' I get an 'Overwritten by Boot Delegation' message :-

Exported Packages    com.google.code.facebookapi,version=3.0.4 com.google.code.facebookapi.apt,version=3.0.4 com.google.code.facebookapi.schema,version=3.0.4 !! com.sun.xml.fastinfoset,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.algorithm,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.alphabet,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.dom,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.org.apache.xerces.util,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.resources,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.sax,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.stax,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.stax.events,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.stax.factory,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.stax.util,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.tools,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.util,version=1.2.13 -- Overwritten by Boot Delegation !! com.sun.xml.fastinfoset.vocab,version=1.2.13 -- Overwritten by Boot Delegation

I see the same thing for another bundle which wraps the jersey client api :-

!! com.sun.jersey.api.client,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.api.client.async,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.api.client.config,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.api.client.filter,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.client.impl,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.client.impl.async,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.client.proxy,version=1.18.1 -- Overwritten by Boot Delegation !! com.sun.jersey.client.urlconnection,version=1.18.1 -- Overwritten by Boot Delegation

I'm certainly no expert but I suspect this has something to do with which classes are loaded when felix starts up. I can see from the sling.properties files for v5.6.1 and v6 that they differ. In v5.6.1 we see the line :-

sling.bootdelegation.sun.reflect=sun.reflect

whereas in v6 :-

sling.bootdelegation.sun=sun.*,com.sun.*

The v6 property explains (I think) why I see the 'Overwritten by Boot Delegation' message, but .... what can I do about it ??

Kind Regards

Fraser.
