Exception in thread "main" java.lang.ClassCastException: class sun.font.CompositeFont cannot be cast to class sun.font.PhysicalFont (sun.font.CompositeFont and sun.font.PhysicalFont are in module java.desktop of loader 'bootstrap') with JAVA 11 on solaris sparc 64 bit. JDK Version :-- 11.0.2

While running our application with JDK 11.0.2 on Solaris Sparc 64 bit , we are getting this exception :-

int w = Math.max(74, toStartButton.getPreferredSize().width+2);

As per this JDK bug ID link :-- https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8132850 it is reolved in JDK 8 and JDK 9 but still we are getting this issue on JDK 11. I double checked the CompositeFont.java class. There the condition is surrounded within try-catch block as mentioned in the solution but still it is not working.

please help.

There is another SO issue raised which is :- OpenJDK 11 java.lang.ClassCastException: class sun.font.CompositeFont cannot be cast to class sun.font.PhysicalFont

    Can you duplicate it with a small test case? It would be good to get it into the bug database. – Alan Bateman Feb 13 '19 at 07:27
