            Bug ID: 2910
           Summary: [IcedTea8] Add rudimentary support for OpenJDK 8 class
                    files to CACAO
           Product: IcedTea
           Version: 8-hg
          Hardware: all
                OS: All
            Status: NEW
          Severity: normal
          Priority: P5
         Component: IcedTea
          Assignee: gnu.andrew at redhat.com
          Reporter: gnu.andrew at redhat.com
                CC: unassigned at icedtea.classpath.org

CACAO currently refuses to handle OpenJDK 8 (version 52.0) class files. A
number of fixes at least get it to read an example OpenJDK 8 class file (a
renamed version of java.lang.reflect.AnnotatedElement which caused CACAO to
crash):

1. Bump the versions supported by CACAO from 1.6.0 and 51.0 to 1.8.0 and 52.0
2. Allow methods inside an interface to be either public or private, rather
than always public + abstract in v52 class files (4.6 of JVM spec).
3. Allow method handle references of type REF_invokeStatic or REF_invokeSpecial
to refer to either a CONSTANT_Methodref_info structure (as before) or a
CONSTANT_InterfaceMethodref_info structure in v52 class files (4.4.8 of JVM
spec)
