Have you tried to restart the app server several times? Maybe it is a classloader problem where it depends on the timing of loading several libs. Maybe some plugins bring with some dublicate jars.

I kind of did as it seems to be working on and off while the only thing we do every night is to restart the app server. I noticed that the OOTB plugin com.appiancorp.webservices.api.axis2-1.0.4 also contains the apache httpclient. How could that interfer and what can I do about it? Thanks, Moritz

We had for example a plugin that contained some older appian libs. After a server restart it could happen that these libs are loaded instead of the ones coming with appian. I think the OOTB plugins should not be a problem as these are tested to work on supported app servers. I checked all plugins in appian/_admin/plugins for jars in the lib folder. Open a support case. Eduardo was of great help last time we had this problem.

In case someone is interested in the solution. Support helped to find that adding the following lines to appian-plugin.xml solved the issue:

<bundle-instructions>
<DynamicImport-Package>META-INF.services,*;resolution:=optional</DynamicImport-Package>
</bundle-instructions>
