SecurityException with accessDeclaredMembers on DatabaseMetaData.getTables.
---------------------------------------------------------------------------
Key: DERBY-656
URL: http://issues.apache.org/jira/browse/DERBY-656
Project: Derby
Type: Bug
Components: Security
Versions: 10.1.1.0
Reporter: Daniel John Debrunner
Assigned to: Daniel John Debrunner
The code to determine the size of a class is using getDeclaredMembers which
requires the permission accessDeclaredMembers. Ideally should not require to
grant this permission to derby.jar. Need to see which
class's size was being calculated. The code is not in a priv block which would
require granting the permission all the way up the stack.
Maybe if the class's declared memebrs can not be accessed and the value can not
be pre-calculkated then some estimate could be made. (using public fields?).
