project_key: EDG

infinispan version: 4.2.1.CR3

When a server side exception occurs in hotrod server, detailed message is not reported back to the client.

I was trying this with replication timeout exceptions.
- I ran 2 edg instances (host1, host2). 
- Placed a breakpoint to DefaultDataContainer.put() on host2
- did one PUT to host1
- This lead to repl. timeout on host1 


This is reported as 
{code}
org.infinispan.client.hotrod.exceptions.HotRodTimeoutException: id [2] code [134] 
{code}
on the client side.
What is missing is the message from the server:
{code}
org.infinispan.util.concurrent.TimeoutException: Replication timeout for localhost-37533
{code}

this seems to be problem on the client side to me,
I couldn't find problems in server code, when debugging. The message is sent correctly to the network. It even appears in wireshark, when I follow the TCP stream of one erroneous put.

the code in the method HotRodOperation.checkForErrorsInResponseStatus()
seems to try to retrieve the error message by means of
transport.readString(), but only "" (zero length string) is returned.
