Choosing the Break on Java Exceptions menu command reveals the Java Exceptions submenu. This submenu contains commands for handling exceptions in the Java programming language. The commands are only available for use with Java source code.

Causes the debugger to break every time an exception occurs. This behavior includes exceptions thrown by the virtual machine, your own classes, the debugger, classes in classes.zip, and so on. Java programs throw many exceptions in the normal course of execution, so catching all exceptions causes the debugger to break often.

Causes the debugger to break only on exceptions thrown by your own classes in the project. Choose this command to break on the exceptions thrown by your classes, rather than on the exceptions that Java programs throw in the normal course of execution.

Causes the debugger to break only on unhandled exceptions.
