Running DBCP 2.9.0 binaries should be used by applications running on Java 8 and above. DBCP 2.4.0 compiles and runs under Java 7 (JDBC 4.1) and above. Here is how it works: Developing DBCP 2.9.0 compiles and runs under Java 8 (JDBC 4.2) and above. (WsFilter.This method calls close() and start() in sequence within synchronized scope so anyĬonnection requests that come in while the datasource is shutting down will be served by the new pool.
