[uml2-dev] [Announce] UML2 5.6.0

[Edward Willink <ed@xxxxxxxxxxxxx>]

Release 5.6.0 is now released and was contributed to SimRel for 2026-03.

UML2 builds are now available from the JustJ page at 
https://download.eclipse.org/modeling/mdt/uml2/builds

(The master branch which is now built automatically every week is now 
set to build 5.6.1).

The 5.6.0 release has no deliberate changes although some changes may be 
observed as a consequence of merging five year old commits on 5.6.0 
master and 5.5.1 maintenance branches. Further subtle changes may result 
from achieving currency with latest Eclipse platform, Java, Tycho and 
Jenkins and using JustJ.

(Use of a modern Eclipse platform of course makes all usage of Java 5 
impossible so the BREE is now Java 8 and the test launches use Java 17. 
Further forced migration is likely.)

Java 8 has an overload problem with the identical static 
PackageOperations.destroyAll() and 
UMLUtil.destroyAll(). PackageOperations.destroyAll() is deprecated. The 
JDT compiler should identify the source incompatibility. The deprecated 
method is retained as a delegation to PackageOperations.destroyAll() so 
that binary compatibility is probably ok.
