Subject [jira] Created: (DERBY-2480) DriverManager.getConnection leaks memory using EmbeddedDriver on non-existent database

DriverManager.getConnection leaks memory using EmbeddedDriver on non-existent database
--------------------------------------------------------------------------------------

                 Key: DERBY-2480
                 URL: https://issues.apache.org/jira/browse/DERBY-2480
             Project: Derby
          Issue Type: Bug
    Affects Versions: 10.2.2.0
         Environment: Windows Vista, JDK 1.4.2_13
            Reporter: Jeff Clary


Repeated calls to java.sql.DriverManager.getConnection("jdbc:derby:C:\\DOES_NOT_EXIST") leak
memory and eventually lead to an OutOfMemoryError.

This bug is similar to DERBY-1947 in that ContextManager objects are not getting removed from
the HashSet.  The attached test program demonstrates the issue.  When run with VM options
-Xms8m -Xmx8m, it throws an OutOfMemoryError after 19022 calls to DriverManager.getConnection.
