Solution for bug 4263113

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4263113 to see the bug.

DriverManager is very slow opening connections.

1) Compile this the DriverManager.java obviously place it under a java/sql folder.

DriverManager.java for JDK 1.5

DriverManager.java for JDK 1.4

1a) javac java/sql/DriverManager.java

2) This will generate DriverInfo.class and DriverManager.class

3) Find the archive in your jdk containing the original DriverManager.java and replace inside the two classes

For example in my system the archive is C:\oracle\jdevstudio1013\jdk\jre\lib\rt.jar

Hope this help!
