        Key: DERBY-23
    Summary: just booting jdbc driver and shutting down seem to leak memory
       Type: Bug

     Status: Unassigned
   Priority: Minor

    Project: Derby
 Components: 
             Services
   Versions:
             10.0.2.0

   Assignee:

Description:
Reporting for Daniel John Debrunner.

Doing simple boot and shutdown of the driver in a loop
seem to grow the heap forever:
new org.apache.derby.jdbc.EmbeddedDriver(); //boot the driver
DriverManager.getConnection("jdbc:derby:;shutdown=true"); 
//shutdown the cloudscape instance completely

after booting and shutting down 1516 times, memory used is  
~~41931056 bytes.
