Research direction

Start with the reported fastjson2 2.0.11 stack trace at JSONFactory.java:330 and JSON.java:52. Reproduce the intermittent NullPointerException and inspect the initialization path for readerProviderLocal. Done means the cause is isolated and the behavior is verified with a reliable reproduction or regression test.
