Re: Thread-safety of buffer allocators in Java


Yes, that is true. Allocators, buffers and pretty much everything inbetween
is thread safe. Locking around the memory backing a buffer itself needs to
be managed in the app. You can review the doc here which talks more about
the structure of the allocators:
