Description

One of the motivations for the new serde format is better error reporting. I was running a test on the new mirror maker when I saw this exception -

java.nio.BufferUnderflowException
at java.nio.Buffer.nextGetIndex(Buffer.java:480)
at java.nio.HeapByteBuffer.getInt(HeapByteBuffer.java:336)
at kafka.common.protocol.types.Type$3.read(Type.java:88)

I was expecting to see a precise error message about the Request type that serde failed for. Instead it says Type$3 and no information on which field.
