Tomek Rękawek updated OAK-5193:
-------------------------------
Description:
When a version is removed, its predecessors and successors are connected
together, to keep the version tree consistent. However, if the removed version
predecessor has its own successors, they are replaced with the removed version
successors. Similarly, if the removed version successor has its own
predecessors, they'll be replaced with the removed version predecessors.
They should be merged together, instead.
was:For a complex version history (in which a version has been restored and
new branch versions have been created), the VersionHistory#remove() may throw
an NPE. Attaching patch containing two test cases.
> VersionHistory#remove() throws NPE for complex version histories
