Andrew Mashenkov commented on IGNITE-7259:
------------------------------------------
Wrong lock order is the issue here.
GridIndexRebuildSelfTest.putData() acquires semaphore permit and then update an
entry under lock,
while SchemaIndexCacheVisitorImpl calls TestRebuildClosure under entry lock
and waits for permits become available inside the closure.
Seems, we should either force visitor to revisit a row or rethink if semaphore
is really needed here.
