testSerializeOpenSimObjects fails sporadically due to randomization #4137
Description
testSerializeOpenSimObjects relies on randomizing the property values of OpenSim objects to test serialization and deserialization. Unfortunately, this can lead to sporadic test failures when the randomized values do not result in a valid configuration. Some of these failures have been patched by the recent PRs #4120 and #4130.
One potential solution would be to introduce an XML schema, as documented in #775. A shorter term solution would be to remove randomization from the tests and use a fixed set of values for testing serialization/deserialization.
