An XSL transformation actually runs in a JVM. Because of this, and because you can use the XSLT debugger to debug Java™ extensions called from your XSL transformation, the Debug view displays JVM threads as if you were debugging a Java application. The XSL transformation will run on the main thread in the JVM. When the transformation suspends on a breakpoint or at the end of a step request, the main thread will suspend and show the stack frames for the XSL transformation. For information about debugging Java extensions and XSL transformations called from Java, see the related topic. In this and other help topics, thread will refer to the Java thread that is executing the XSL transformation.
