[OpenJDK 2D-Dev] Review Request for JDK-7107905: equals() method in IndexColorModel doesnt exist and it relies on ColorModel.equals() which is not strict

[Jayathirth D V]

Hi, 

 

Please review the following fix in JDK9:

 

Bug : https://bugs.openjdk.java.net/browse/JDK-7107905 

 

Webrev : http://cr.openjdk.java.net/~jdv/7107905/webrev.00/ 

 

Issue : When we compare two IndexColorModel objects with different ColorMap(or any other property specific to IndexColorModel) using equals() method it returns true.

 

Root cause : There is no override equals() method specific to IndexColorModel and it uses super class equals() which is ColorModel and it doesn't verify equality for IndexColorModel specific properties.

 

Solution : Add override equals() method for IndexColorModel which verifies its unique properties for equality.

  

Thanks,

Jay
