Description
The CR 6749517 introduced an API to control the position of the AWT security warning. The com.sun.awt.SecurityWarning.getSize() method is supposed to return the current size of the warning for a given window. It's been noticed that the variables that hold the size of the warning get only updated on MS Windows platform. The X11 implementation of the enhanced security warning does not update the values which results in returning zero size all the time.

                                    

Comments
EVALUATION

Need to update the internal variables whenever the size of the warning changes.
