FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195] Service Pack 2

EXTRA RELEVANT SYSTEM CONFIGURATION :
Connecting to an SQL Server 7 database.

A DESCRIPTION OF THE PROBLEM :
If you call ResultSet.close on a ResultSet returned by Connection.getMetaData after you close the Connection used, the virtual machine crashes with EXCEPTION_ACCESS_VIOLATION.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the attached test program: java TestDB
sun.jdbc.odbc.JdbcOdbcDriver jdbc:odbc:<odbc data source> <user>
<password>

EXPECTED VERSUS ACTUAL BEHAVIOR :
No output, or an SQLException. With J-netdirect's JSQLConnect driver,
there is no output, but I guess an SQLException would be reasonable.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal :EXCEPTION_ACCESS_VIOLATION occurred at PC=0x41249C2E
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
      just occurred. Please refer to release documentation for possible
      reason and solutions.
