building classpath on RedHat2.6.11

[Seeta somagani]

Hi, I configured classpath on RedHat2.6.11 using --disable-gtk-peer option. But when I'm tryin to gmake, it gives me an error
/java/security/Provider.java:57: error: Can't subclass final classes: gnu.java.security.Properties.

Is there a fix for this?
Thanx
