Bryan Pendleton commented on DERBY-2480:
----------------------------------------
In addition to John's new test, all the existing regression tests ran cleanly
for
me with the two patches applied.

> 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.
