kendzi3d plugin broken since josm-snapshot-15007

[cmuelle8]

Hi, removing deprecated API in changeset 15007 broke kendzi3d plugin. rev15000 still worked.

@Don-vip: It is relatively easy to reintroduce the method in question (with the deprecation warning). Can you please restore it, until kendzi3d plugin has been indeed been migrated to using ReflectionUtils#setObjectsAccessible(AccessibleObject...)?
