Thanks Simone.

As per your suggestion,Before invoking http2 post,I have set Web application class loader manually to JMS consumer thread, then it worked .

Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

Thanks

Hi Simone Bordet,

We have below libraries in WEB-INF/lib

jetty-alpn-openjdk8-client-9.4.35.v20201120.jar
jetty-alpn-client-9.4.35.v20201120.jar
jetty-client-9.4.35.v20201120.jar
jetty-http-9.4.35.v20201120.jar
jetty-io-9.4.35.v20201120.jar
jetty-util-9.4.35.v20201120.jar
http2-http-client-transport-9.4.35.v20201120.jar
http2-hpack-9.4.35.v20201120.jar
http2-client-9.4.35.v20201120.jar
http2-common-9.4.35.v20201120.jar

This exception (java.lang.IllegalStateException: No Client ALPNProcessors!
) happening only when i invoke http2 post request
from JMS Consumer thread. We use IBM MQ, once message is consumed from
Queue , using the same consumer thread
we are making an http2 post request using jetty library.

I debugged and found that ServiceLoader.load() is not loading this service
org.eclipse.jetty.alpn.openjdk8.client.OpenJDK8ClientALPNProcessor
eventhough jetty-alpn-openjdk8-client-9.4.35.v20201120.jar is in
WEB-INF/lib.

JMS Consumer thread is using java.net.URLClassLoader@49e202ad . Please let
us know what could be the root cause for this issue.

Thanks
Prakash

Could be that the JMS consumer thread does not set properly the thread
context classloader.

Try to set it manually before you make the HTTP/2 call, setting it to
the web application classloader.
