Brian Clozel 07d2571e0b Avoid race conditions while restructuring ConcurrentReferenceHashMap Prior to this commit, the `ConcurrentReferenceHashMap#restructure` operation would null out the entire references array before starting the restructuring operation (in case resizing is not necessary). This could cause at runtime race conditions where a lookup operation would return null, when the value is actually cached but not accesible during the restructuring phase. This commit ensures that, when resizing is not required, a new reference list is built (purged of null entries) and then assigned to the reference array. This way, concurrent reads will not return null for existing entries and there are less chances of re-calculating cache entries during the restructuring phase. Closes gh-31008	2 years ago

Prior to this commit, the `ConcurrentReferenceHashMap#restructure`
operation would null out the entire references array before starting the
restructuring operation (in case resizing is not necessary).

This could cause at runtime race conditions where a lookup operation
would return null, when the value is actually cached but not accesible
during the restructuring phase.

This commit ensures that, when resizing is not required, a new reference
list is built (purged of null entries) and then assigned to the
reference array. This way, concurrent reads will not return null for
existing entries and there are less chances of re-calculating cache
entries during the restructuring phase.
