Subject: [Bug libgcj/17013] gij vtable layout: hidden package-private method can be overridden
Date: Thu, 12 Aug 2004 22:10:00 -0000	[thread overview]

_Jv_LayoutVTableMethods() needs to check that classes are in the same package
before allowing a pkg-private method to be overriden. vtable layout for BC-ABI
most likely has the same bug. There is a FIXME in the code for this:

      // FIXME: Must check that we don't override:
      // - Package-private method where superclass is in different package.
      // - Final or less-accessible declaration in superclass (check binary 
      //   spec, do we allocate new vtable entry or put throw node in vtable?)
      // - Static or private method in superclass.
