Math.max(getWidth() - this.insets.left - this.insets.right, getWidth()) can give incorrect result for the case where a component size is 50x50 and insets are [10, 10, 10 , 10]. max(50-10-10, 50) = 50 but the expected results is 30.

The correct formula should be max(width-insets.left-insets.right, minWidthValue) where minWidthValue is zero or some specified minimal value.

The DiagramComponent.paintComponent() code tries to create an array of size width*height and BufferedImage with component size. In this case it may be better just to check that the component size minus insets is
greater than zero. If it is less or equal to zero we can just return from the paintComponent() method.

Thanks,
Alexandr.

Hi,

Please review fix for JDK9,

Bug: https://bugs.openjdk.java.net/browse/JDK-8152419 

Webrev: http://cr.openjdk.java.net/~pkbalakr/8152419/webrev.00/ 

 

  

Issue:

JColorChooser throws Exception(NegativeArraySizeException)

 

Fix:

Absolute value is passed while creating array.

   If component size is 10x10 and insets are [30, 30, 30, 30] the absolute value of the difference will be  abs(10 - 30 - 30)=50.
   It seems that the right component size should be zero or some minimal values which is max(width-insets.left-insets.right, minWidthValue).

  Thanks,
  Alexandr.
