Pinpoint java agent 3.0.4

Describe the bug

we are trying to upgrade Pinpoint from version 2.5.2 to v3.0.4. we have JBOSS application running with Apache Karaf / Fuse OSGi environments. agent silently fails during application start up with below exceptions -

ClassNotFoundException: jakarta.servlet.AsyncListener ClassNotFoundException: com.navercorp.pinpoint.bootstrap.instrument.Instrumentor ClassNotFoundException: com.navercorp.pinpoint.common.util.VarArgs ClassNotFoundException: com.navercorp.pinpoint.bootstrap.plugin.util.InstrumentUtils ClassNotFoundException: com.navercorp.pinpoint.bootstrap.async.AsyncContextAccessor ClassNotFoundException: com.navercorp.pinpoint.bootstrap.config.Filter

main issue is having ClassNotFoundException: jakarta.servlet.AsyncListener exception

OSGi sees those references → tries to load Jakarta classes → but Fuse only has javax.

✔ Pinpoint injects bytecode containing references to Jakarta async classes ✔ It injects references to bootstrap-only classes (Instrumentor, Filter, VarArgs, ExecutionPolicy, etc.) ✔ OSGi tries to load these inside bundles (ActiveMQ, CXF, Hawtio) ✔ OSGi cannot see bootstrap classloader ✔ Therefore: CNFE is unavoidable

Expected behavior

v3.0.4 should be compatible with OSGi class loading
