Test serialization of EclipseProject model TAPI proxies - use trait with "loadEclipseProjectModel" method
- test serialization only on clients above 2.11 (2.12+) - TAPI proxy serialization is broken in older client versions
- don't check the result of serialization, only make sure all objects in the object graph are serializable - serialization end-to-end check would require using PayloadSerializer which seems to cause problems with the cross-version TAPI test classloader setup - attempt to check the whole serialization roundtrip is in commit b6d484cf , that was reverted by c9d61094
Revert "Revert "Guarantee entry order of Project.getChildProjects() (by-name)."" - bring back the guaranteed entry order of Project.getChildProjects() - fix the integration tests that failed earlier This reverts commit d6d874a34fc8f0abd6a055d2553a3eae8fec2a6a.
