PoolingDataSource.PoolGuardConnectionWrapper equals() implementation incorrect
------------------------------------------------------------------------------
Key: DBCP-198
URL: http://issues.apache.org/jira/browse/DBCP-198
Project: Commons Dbcp
Issue Type: Bug
Affects Versions: 1.2.1
Reporter: Kevin Ruland
The Object.equals( Object ) implementation in
PoolingDataSource.PoolGuardConnectionWrapper is broken because it does not
attempt to test if the outermost objects are equal. It should be replaced with
something like:
public boolean equals(Object obj) {
if ( obj == this ) return true;
if ( obj instanceof PoolGuardConnectionWrapper ) {
return delegate.equals( ((PoolGuardConnectionWrapper) obj).delegate );
return false;
}
The current implementation prevents putting PoolGuardConenctionWrapper objects
in Collections and using the standard contains( Object ) or remove( Object )
methods.
