The bug fix for 6714797 that was integrated into B01 of jdk6u12 has introduced some new abstract interface methods to some corba interfaces. Although the corba changes seem to be in the latest glassfish versions.

When the jdk7 corba repository is built against these newer interface class files, the corba build is failing, not sure why it's not using the classes from it's own build.

The errors:

src/share/classes/com/sun/corba/se/impl/transport/SocketOrChannelConnectionImpl.java:95: com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl is not abstract and does not override abstract method closeConnectionResources() in com.sun.corba.se.spi.transport.CorbaConnection

Using jdk6u11 or older works fine.
