Connection.java: Use GetPropertyAction for privileged getProperty calls.

Browse source 
2004-07-23  Bryce McKinlay  <mckinlay@redhat.com>

	* gnu/java/net/protocol/http/Connection.java: Use GetPropertyAction
	for privileged getProperty calls.
	* java/io/ObjectOutputStream.java (getField): No longer static. Use
	SetAccessibleAction instead of anonymous class for doPrivileged
	call.
	(getMethod): Likewise.
	(setAccessible): New field. PrivilegedAction object to use when
	calling setAccessible.
	* java/io/ObjectStreamClass.java (calculateOffsets): Use
	SetAccessibleAction instead of anonymous class for diPrivileged
	call.
	(setFields): Likewise.
	(getClassUID): Likewise.
	(findMethod): Likewise.
	* gnu/java/security/action/GetPropertyAction.java: New class.
	* gnu/java/security/action/SetAccessibleAction.java: New class.
