The most important part of this PR is the fix for
unregisterTypeConversion(Conversion<?>)
where either a NPE would be thrown if aConversion#getTypeKeys
returned null, or it simply would not unregister the conversion if the instance passed is not the same instance as what was originally registered.Other changes were minor:
unregisterTypeConversion(Object)
to be next to its overloadUnmodifiableMap
wrapping a newLinkedHashMap
to be precise)All unit tests pass.
