Subject: [Pljava-dev] How to configure security manager?

Apparently the third-party code I'm using is trying to do this:

        java.security.Security.addProvider(
            new com.sun.net.ssl.internal.ssl.Provider());
        System.setProperty( "java.protocol.handler.pkgs", 
            "com.sun.net.ssl.internal.www.protocol" );

It's necessary to open https URL connections. Essentially, what I'm trying to 
do is write a trigger that relays data inserted into a table to a MSN instant 
message account. This is the only place it tries to set a system property. Is 
there a way I can set system properties from the postgres.conf file or pljava 
such that the JVM the trigger is running in will see them?
