 Note: You need to use ppudump of the same version as the FPC compiler. Use the -D switch to specify correct ppudump if it is not in PATH.
 
+CUSTOM HANDLERS
+
+It is possible to define the following custom handlers in your Pascal code.
+
+procedure JNI_OnException;
+  - is called when an unhandled Pascal exception occurs. For example, you can log a stack back trace in this handler.
+
+Custom handlers must be public and defined in one of the main units specified when calling pas2jni.
+
+CODING TIPS
+
+* Setting handlers (method pointers) in a Java code.
+
+For example there is the following event handler in your Pascal code:
+
+TMyClass = class
+...
+  property OnChange: TNotifyEvent;
+...
+end;
+
+In a Java code you get the following TMyClass instance:
+
+TMyClass myclass = TMyClass.Create();
+
+It is possible set a Java handler in 2 ways:
+
+1) Place the handler inline.
+
+...
+  myclass.setOnChange(
