After Jetty Update to 9.4.x: Missing Constraint: Require-Capability: osgi.extender; filter:="(osgi.extender=osgi.serviceloader.processor)"

Question

After updating from Jetty 9.3.x to 9.4.x I'm getting the following validate message when I launch my OSGi Framework launch:

Missing Constraint: Require-Capability: osgi.extender; filter:="(osgi.extender=osgi.serviceloader.processor)"
Missing Constraint: Require-Capability: osgi.extender; filter:="(osgi.extender=osgi.serviceloader.registrar)"

I can't figure out the bundles I have to add?

Already included in the launch (among many others):

• org.eclipse.jetty.client
• org.eclipse.jetty.continuation
• org.eclipse.jetty.deploy
• org.eclipse.jetty.http
• org.eclipse.jetty.io
• org.eclipse.jetty.rewrite
• org.eclipse.jetty.security
• org.eclipse.jetty.server
• org.eclipse.jetty.servlet
• org.eclipse.jetty.servlets
• org.eclipse.jetty.util
• org.eclipse.jetty.webapp
• org.eclipse.jetty.xml
• org.eclipse.osgi
• org.eclipse.osgi.services
• org.eclipse.osgi.util

The server launches without error messages after clicking "OK" in the dialog.
I hoped this issue would be fixed in Jetty 9.4.5 but it remains.

Answer 1

I had to download and add the following three bundles to the target:

• org.apache.aries.spifly.dynamic.bundle
  
• org.apache.aries.util
  
• asm-all
  

As described on the Apache Aries SPI Fly website, section Getting SPI Fly.

Since I do not want to manipulate the bytecode I choose "For use with dynamic weaving".

Answer 2

It appears you need an implementation of the OSGi Service Loader Mediator specification. Try Apache Aries SPI Fly.
