Service C code and security manager problem

[Nick Betteridge]

I'm trying to set up catalina as a service running as a daemon and
implement the security manager.

I've hit a problem which is that arguments.c in
{catalina_src)/server/native :

a)  doesn't provide for more than 1 '=' sign in a -D property (needed
for -Djava.security.policy==/../../../conf/catalina.policy)

b)  doesn't provide for a null argument to a -D property (needed for
-Djava.security.manager)

Has anyone written a work around for this?

Thanks

NIck
