[equinox-dev] NullPointerException in org.eclipse.equinox.launcher.Main$

["Pepping, Florian" <florian.pepping@xxxxxxxxxxxxxxxxxx>]

Hello,

using the FrameworkSecurityManager of Equinox, I get a
NullPointerException during a permission check using Java 1.5.
Using exactly the same code, starting the application with Java 1.6,
everything works fine.
Stepping through the code in EclipsePolicy, it seems, that the
CodeSource of the ProtectionDomain to be checked against is null.
Referring to the Javadoc, this is normal behaviour and allowed but the
EclipsePolicy does not check this.

Is this a bug or am I doing something wrong? Currently I've have no idea
what to do, to avoid this Exception.

Below you find the StackTrace of the exception occuring.
