Fix circular dependency between AtomicReference and Synchronization::Object #982

Closed eregon closed 1 year ago

eregon commented 1 year ago

Do not depend on Synchronization::LockableObject for MutexAtomic{Reference,Fixnum,Boolean}
Extract safe initialization and use it for MutexAtomic{Reference,Fixnum,Boolean}

TODO:

[x] Check what gets defined by the JRuby extension, might need more require 'concurrent/utility/native_extension_loader' # load native parts first for JRuby
[x] Audit usages of java_extensions_loaded?
