You can test Java AWT/Swing applications using the Classic Agent or the Open Agent. When you create a new Java AWT/Swing project, Silk Test Classic uses the Open Agent by default. However, you can use both the Open Agent and the Classic Agent within a single Java AWT/Swing environment. Certain functions and methods run on the Classic Agent only. As a result, if you are running an Open Agent project, the Classic Agent may also open because a function or method requires the Classic Agent.
When you are using the Classic agent to test Java AWT/Swing applications, Silk Test Classic uses the Sun JDK by default.
