Hi,
I am getting the following java.lang.VerifyError when loading a GWT
Module. I am using GWT 2.0.2 and AppEngine 1.2.1. The stack trace of
the error is as follows.
10:58:38.406 [ERROR] [sensormss] Unable to load module entry point
class com.sensorms.client.Sensormss (see associated exception for
details)
java.lang.VerifyError: (class: com/google/gwt/core/client/Scheduler,

I get this only when I use any of the Layout Panel stuff. This code
caused this error to occur. It was taken from the TabLayoutPanel
Javadoc example.
TabLayoutPanel p = new TabLayoutPanel(1.5, Unit.EM);
p.add(new HTML("this"), "[this]");
p.add(new HTML("that"), "[that]");
p.add(new HTML("the other"), "[the other]");
RootLayoutPanel rp = RootLayoutPanel.get();
rp.add(p);
Kindly let me know what causes the error. Even the Appengine SDK 1.3.1
causes this error.
Any help/suggestions are appreciated. Thanks in Advance.
Regards,
Shyam Visamsetty.
