    We can either just include this as a warning as part of Release Notes or we 
can roll this change back. I am fine with including just a Release Note to warn 
all users trying to upgrade unless others thing Rolling upgradability is 
important enough that we only brake it when people move between major versions.

> STORM-1220 introduced some changes where in one place it passes ByteBuffer as 
> is instead of byte[]. Existing bolts that expects a byte[] fails due to this 
> with "java.lang.RuntimeException: java.lang.ClassCastException: 
> java.nio.HeapByteBuffer cannot be cast to [B "
