exec:java squelches the first AWT exception
-------------------------------------------
Key: MEXEC-80
URL: http://jira.codehaus.org/browse/MEXEC-80
Project: Maven 2.x Exec Plugin
Issue Type: Bug
Components: java
Affects Versions: 1.1.1
Environment: Reproducible on Mac OS X 10.6.3 and Windows XP SP3, both
with Java 1.6.0_20
Reporter: Trevor Harmon
Attachments: tracetest.zip
When using exec:java to launch a Java program, the first exception that occurs
in an AWT thread is squelched. Only the second and subsequent exceptions appear
in the console. This does not happen if the same program is executed outside of
the Maven environment.
A simple test case is attached to demonstrate this behavior. To run: "mvn
install exec:java". You will see a window with a button. Clicking the button
causes a java.lang.ArithmeticException to be thrown, but the exception does not
appear in the console. Clicking the button again causes a second exception to
be thrown. This time it does appear.
This behavior has been reproduced on Maven 2.2.1 and Maven 3.0-beta-1.
Run the same program outside of Maven with: "java -cp target/classes
TraceTest". The exception will appear the first time you click the button. This
is the expected behavior.
