albert Steiner created NETBEANS-4549:
----------------------------------------
Summary: class javax.swing.DebugGraphics cannot be cast to class
java.awt.Graphics2D
Key: NETBEANS-4549
URL: https://issues.apache.org/jira/browse/NETBEANS-4549
Project: NetBeans
Issue Type: Bug
Components: javaee - Code
Affects Versions: 11.3
Environment: Windows 10, with netbeans 11.3 set to global library open
Java 14
Reporter: albert Steiner
Attachments: StarTrader.java
I have worked on this code, a few hours a week for 9 years, so there is a lot
of history
The code works for Java1.8_251 but not for open java 13,14,15 Error occurs as
part of initialization of the program, producing a panel with tabs. I produces
a blank panel and a fatal exception.
I don't know if this is a Java bug or a bug in the display code generated over
the 9 years, so I'm posting this as a possible open netbeans bug.
