MIDlet.getAppProperty throws exception for missing JAD prop #12

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Running the August 18 2009 v3.0.0 SNAPSHOT emulator locally on the
apps/microemu-demo.jad "java -jar microemulator.jar
-Xautotest:http://localhost:8000/microemu-demo.jad" with JRE 1.6.0_13 where
the JAD is modified to point "MIDlet-Jar-URL:
http://localhost:8000/microemu-demo.jar" and using a local web server on
Mac OSX 10.5 "python -m SimpleHTTPServer" in the apps/ folder the emulator
throws:

This exception should not be thrown by getAppProperty.

http://java.sun.com/javame/reference/apis/jsr118/javax/microedition/midlet/
MIDlet.html#getAppProperty%28java.lang.String%29

A missing JAD property, in this case "microemu.accessible.host", should
result in getAppProperty returning a null String.

Further, Sun says a NullPointerException will be thrown by getAppProperty
when the parameter passed into the method is null. I believe Sun should
have thrown an IllegalArgumentException here.

MicroEmulator's getAppProperty should return a null String.
