Hi Team, I have upgraded netty-handler jar version recently from 4.1.77.Final to 5.0.0.Alpha2 but looks like my GRPC call is getting failed in between because of this upgrade.
After upgrading the above jar below is flow where it is getting failed. Issue is with the method *toInternalLevel *present in LogLevel class under netty-handler jar. In earlier version(4.1.77.Final) of this jar this method had access modifier as public but in current version(5.0.0.Alpha2) public access modifier has been removed and because of that I am getting below exception. "stackTrace": "java.lang.IllegalAccessError: tried to access method io.netty.handler.logging.LogLevel.toInternalLevel()Lio/netty/util/internal/logging/InternalLogLevel; from class io.netty.handler.codec.http2.Http2FrameLogger\n\tat io.netty.handler.codec.http2.Http2FrameLogger.checkAndConvertLevel(Http2FrameLogger.java:63)\n\tat io.netty.handler.codec.http2.Http2FrameLogger.<init>(Http2FrameLogger.java:54)\n\tat io.grpc.netty.NettyClientHandler.newHandler(NettyClientHandler.java:201)\n\tat io.grpc.netty.NettyClientHandler.newHandler(NettyClientHandler.java:158)\n\tat io.grpc.netty.NettyClientTransport.start(NettyClientTransport.java:217)\n\t... 9 frames truncated\n\t... 3 common frames omitted\nWrapped by: io.grpc.StatusRuntimeException: INTERNAL: Panic!
