Re: [grpc-io] SSL error with GRPC Java

[mgthrisha]

thank your the reply. Yes it is osgi bundle.

It was the issue with OSGI bundle framework[Felix] unable to load OS 
dependent DLL file. These DLLs have implementation specific to OS. I have 
upgraded to latest Felix framework which has native loading capability. 
 That resolve the issue

Re: [grpc-io] SSL error with GRPC Java

['Eric Gribkoff' via grpc.io]

This is for an OSGi bundle? It looks like the errors you're getting are
internal to Netty, and indicate that your bundle is not correctly adding
netty-tcnative to the classpath. I don't have any experience with OSGi, but
you may be able to get help with the class loading issue at
https://github.com/netty/netty.
