The test does an ImmutableDescriptor.union() on an Immutable descriptor and a modelmbean.DescriptorSupport descriptor with the same field name, equal case, and different values; it expects an IllegalArgumentException.
IllegalArgumentException was thrown up to b38.
With b39, we do not receive any exception.

Test output is:

(TEST) Two Immutable descriptor with the same field name, equal case, and different values
(TEST) [{a=b}, {a=c}]
(OK) Received IllegalArgumentException

(TEST) Two modelmbean.DescriptorSupport descriptor with the same field name, equal case, and different values
(TEST) [a=b, a=c]
(OK) Received IllegalArgumentException

(TEST) One Immutable descriptor and one modelmbean.DescriptorSupport descriptor with the same field name, equal case, and different values
(TEST) [a=b, {a=c}]
(ERROR) Did not receive IllegalArgumentException
