Init a *PUBLIC* *STATIC* field via an instances constructor without any
syncronization can't be called bad style anymore... is a call for trouble!
(btw your defaultconstructor shoudl really use constructor delegation ...)

new Database("/data/test", 100);
System.out.println("object >>> " + Database.this);

public Connection getDbConnection() throws SQLException

Probably because your code is instantiating your
com.atr.media.db.Database object via the default constructor,
which does
not initialise the poolMgr field?
