The core.network/external/nsProxyAutoConfig.js isInNet function is broken under Java8. In Java8 the embedded script engine is no longer support shortened regexp matching: /^something$/(anything) so it needs to be changed to /^something$/.exec(anything) or the whole configuration script handling can be rewritten in pure java to evade bugs like this.
