Re: BufferUnderflowException on GridRedisProtocolParser
Hi Stan, Thanks for the suggestion. I have tried to patch it, which would work 95% of the case, but would run into another random issue. I have mailed dev list for suggestions.

RE: BufferUnderflowException on GridRedisProtocolParser
Well, you need to wait for the IGNITE-7153 fix then. Or contribute it! :) I checked the code, and it seems to be a relatively easy fix. One needs to alter the GridRedisProtocolParser to use ParserState in the way GridTcpRestParser::parseMemcachePacker does.
