The fix for ISPN-7959 appears to have been accidentally reverted in commit 646516309ca6c7862052cf7b1a14abb669de3d92 for ISPN-9849.

Logging of WrappedByteArray (for example logging PutKeyValueCommand's key and value in "ISPN000071: Caught exception when handling command"...) logs the entire value, which can be humongous.
(Double the size of the binary value, which is causing 50+MB log lines in one case).
