> Most of the FsShell commands catch exceptions and then just print out an error like "foo: " + e.getLocalizedMessage(). This is fine when the exception is "user-facing" (eg permissions errors) but in the case of a user hitting a bug you get a useless error message with no stack trace. For example, something "chmod: null" in the case of a NullPointerException bug.
> It would help debug these cases for users and developers if we also logged the exception with full trace at DEBUG level.
