A DESCRIPTION OF THE PROBLEM :
Making java.awt.FileDialog and doing setVisible(true) results in a Mac OS error message to console for FileDialog.LOAD option (not .SAVE option)

java[693:9501] Unable to simultaneously satisfy constraints... [lists various NSAutoresizingMaskLayout constraints].

Looks very similar to a bug reported earlier this year (JDK-8074185 ?) which was closed as unreproducible.

REGRESSION. Last worked in version 7u75

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
$cat <ConstraintTroubleAwtFileDialog.java
public class ConstraintTroubleAwtFileDialog extends javax.swing.JFrame {
public static void main(String[] args) {
javax.swing.JFrame appJFrame = new javax.swing.JFrame("AWT File Dialog Mac Console Warning");
appJFrame.setSize(400, 400);
appJFrame.setVisible(true);
java.awt.FileDialog iFileDialog = new java.awt.FileDialog(appJFrame, "Input File", java.awt.FileDialog.LOAD);
iFileDialog.setVisible(true);
}
}
$javac ConstraintTroubleAwtFileDialog.java
$java ConstraintTroubleAwtFileDialog
... error message displays ...


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Should run without any error message.
ACTUAL -
$java ConstraintTroubleAwtFileDialog
    [screen shows empty JFrame window, then text below appears in the Mac Terminal window and finally the correct FileDialog box appears]

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens. And/or, break on objc_exception_throw to catch this in the debugger.

CUSTOMER SUBMITTED WORKAROUND :
Either have to tolerate error output, or switch to JFileChooser; however, JFileChooser is unfamiliar to many Mac users.
