Bug #35810 Connection URL parameters are ignored when using MysqlConnectionPoolDataSource

Description:
JDBC connection URL parameters are ignored when using MysqlConnectionPoolDataSource.

For example same URL:

jdbc:mysql://host:3306/db?connectTimeout=1000

causes timeout when using Driver.getConnection, but connection hangs when using MysqlConnectionPoolDataSource.

How to repeat:
Find a host that causes connection timeout.

String url = "jdbc:mysql://host:3306/db?connectTimeout=1000"

Execute

===
DriverManager.getConnection(url, "user", "password")
===

You will have exception after 1 second. It's OK. Then execute:

===
ds = new MysqlConnectionPoolDataSource();
ds.setUrl(url);
ds.setUser("user");
ds.setPassword("password");
ds.getPooledConnection()
===

Connec will hang.

Suggested fix:
Probably, you should drop line

===
exposeAsProperties(props);
===

from MysqlDataSource.getConnection(String, String).
