Phil Steitz commented on DBCP-300: ---------------------------------- A workaround is to "manually" construct a PoolingDataSource as in the ManualPoolingDataSourceExample linked under Examples on the dbcp home page. This issue will be a little tricky to "fix" given the lazy initialization and (supposed) property mutability of BasicDataSource. One thing we should consider is deprecating BasicDataSource and replacing it with a class whose properties (other than closed) are immutable. > remove synchronize access of createDataSource > --------------------------------------------- > > Key: DBCP-300 > URL: https://issues.apache.org/jira/browse/DBCP-300 > Project: Commons Dbcp > Issue Type: Improvement > Affects Versions: 1.2.2 > Environment: RHEL, jdk1.5.0_12, commons-dbcp 1.2.2 > Reporter: Nikhil Singh > > For JDK1.5 onwards we can make the DataSource volatile and start using > "double checked locking" idiom.
