URL: https://github.com/apache/activemq-artemis/pull/3295#issuecomment-724012224
Hi Justin,
the "PagingStoreFactory::newFileFactory" is a reference to the interface
method that is, transitively, the root of the problem, here.
Its signature reads:
SequentialFileFactory newFileFactory(SimpleString address) throws
Exception;
Mere
`` return false;
could be an option but I hesitate until sure that exceptions can be silently
swallowed. That's why I rather suggest to combine with the assert: to fail
fast.
Hope it helps
