A DESCRIPTION OF THE PROBLEM :
When you filled the texture with the zoomed picture, an internal exception occurred.
There is a similar bug in the bug Database, which has been closed because the sample couldn't reproduce. https://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8072618
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Generate demo.jar from the project, and place any Image 1.jpg to the same level directory of TextureComponent1.class
2. java -jar demo.jar
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Exception in thread "AWT-EventQueue-0" java.lang.InternalError: Surface not cachable
