Sam Brannen f5d36aa47a Revert use of Map::computeIfAbsent in thread and tx scopes Issues gh-25038 and gh-25618 collectively introduced a regression for thread-scoped and transaction-scoped beans. For example, given a thread-scoped bean X that depends on another thread-scoped bean Y, if the names of the beans (when used as map keys) end up in the same bucket within a ConcurrentHashMap AND an attempt is made to retrieve bean X from the ApplicationContext prior to retrieving bean Y, then the use of Map::computeIfAbsent in SimpleThreadScope results in recursive access to the same internal bucket in the map. On Java 8, that scenario simply hangs. On Java 9 and higher, ConcurrentHashMap throws an IllegalStateException pointing out that a "Recursive update" was attempted. In light of these findings, we are reverting the changes made to SimpleThreadScope and SimpleTransactionScope in commits `50a4fdac6e` and `148dc95eb1`. Closes gh-25801		5 years ago
