FULL PRODUCT VERSION :
1.6.0-beta-b59g
ADDITIONAL OS VERSION INFORMATION :
Windows 6.0.5384
A DESCRIPTION OF THE PROBLEM :
Whenever a Java Applet attempts to run a command using Runtime.exec(), an IOException error is thrown:
java.io.IOException: CreateProcess: <command> error=5
Apparently, "error=5" means "Access Denied". The applet is signed and trusted by the user. The same applet works fine in IE7 on Windows XP.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile the included source code.
2. Put the .class file into a signed JAR file.
3. Run the applet from a simple test page:
<html>
<head>
<title>Run a command via an applet</title>
</head>
<body>
<applet code="RunCommand.class" archive="RunCommand.jar" width="1" height="1">
<param name="cmd" value="ipconfig">
</applet>
</body>
</html>
4. View the console output.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The console should show the output of the command that the applet ran (ipconfig)
ACTUAL -
The IOException is displayed.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
java.io.IOException: CreateProcess: ipconfig error=5
REPRODUCIBILITY :
This bug can be reproduced always.
