Description
Currently when type systems are merged across annotators, the ordering of the types produced by the merge method is not defined, and varies according to the ordering in which the individual type system descriptors are passed to the merge method. The ordering depends on the order in which individual AEs are initialized, which is also not defined, and may even vary according to JVM version.
One reason to improve this is that UIMA-AS has a feature to allow binary serialization, but it requires that type systems be identical on both sides of the connection, and it is difficult to ensure this if ordering cannot be relied on.
