Question: How to solve the java.lang.AbstractMethodError exception?

See original GitHub issue

Hi all, when I use gRPC in karaf environment, it always throw an exception(AbstractMethodError), can someone help me or give me some advice, thanks.

About AbstractMethodError exception:(https://docs.oracle.com/javase/7/docs/api/java/lang/AbstractMethodError.html) Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

Or the Netty BOM 🎉

You’re mixing Netty modules with different/incompatible version:

io.netty:netty-codec-http2:jar:4.1.16.Final:compile (version selected from constraint [4.1.16.Final,4.1.16.Final])
[INFO] |  |  |  +- io.netty:netty-codec-http:jar:4.0.37.Final:compile

You must keep all of them aligned (4.1.16 everywhere), eg with some dependencyManagement config in maven.
