Gary Gregory updated LOG4J2-2612:
---------------------------------
Description:
A NullPointerException can be thrown at
{{org.apache.logging.log4j.core.appender.db.jdbc.JdbcDatabaseManager.writeInternal(JdbcDatabaseManager.java:803)}}
This seems to happen if {{writeInternal()}} runs at the same time as either a
reconnect or the appender shutting down.
