SYMPTOMS

A JET-compiled application does not print stack backtrace to standard output when an uncaught exception is thrown by one of its threads or when a printStackTrace() method is called explicitly.

CAUSE

By default, stack trace printing is disabled in the JET runtime system (Throwable.printStackTrace() methods do nothing.)

RESOLUTION

To enable stack trace, set the jet.stack.trace system property, for instance:

  SET JETVMPROP=-Djet.stack.trace
  MyJavaApp.exe

Using the Control Panel, you may specify the property on the Target page: type jet.stack.trace in the System Properties field and recompile the application.

Note: Enabling stack trace may negatively impact performance, if exceptions are thrown and caught repeatedly.

The jet.stack.trace setting enables printing stack traces that contain only class names. If you need a detailed information including method names and line numbers, add this option

-GENSTACKTRACE+

to the beginning of the project file and recompile your application.

Note: The side effect of setting GENSTACKTRACE ON is the substantial growth (20% or more) of the resulting executable size.
