           Summary: ICE:  bytecode-to-native compiler cannot find interface
                    methods on abstract implementing classes
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: java
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: tv at pobox dot com
                CC: gcc-bugs at gcc dot gnu dot org

===== I.java =====
public interface I { void foo(); }

===== A.java =====
public abstract class A implements I {}

===== C.java =====
class C { void foo(A a) { a.foo(); } }

===== commands =====
$ gcj -C *.java
$ gcj -c C.java && echo "it worked"
it worked
$ gcj -c C.class
C.java: In class `C':
C.java: In method `C.foo(A)':
C.java:1: error: class 'A' has no method named 'foo' matching signature '()V'
C.java: In constructor `()':
C.java:0: internal compiler error: tree check: accessed elt 0 of tree_vec with 2 
elts in find_local_variable, at java/decl.c:200

===== comments =====
Happens on gcj 3.3, with the difference of the C.java:0: error line:

C.java:0: confused by earlier errors, bailing out

This prevents compilation of the binary Cryptix JCE and Sun JSSE .jar files 
because they can't find java.security.cert.X509Certificate.
getCriticalExtensionOIDs() (which is actually defined in java.security.cert.
X509Extension, implemented by X509Certificate).

Note that compiling from Java source does work (gcj -c C.java, above), but JSSE 
is not available in source form.

Er, forgot to mention that the actual commands posted in the example run of this 
testcase were against gcc cvs HEAD as of 2003/06/25.

I can confirm this on 3.0.4, 3.2.3, 3.3.1 (20030616) and the mainline (20030626).
If I use Sun's 1.4.1 to compile C.java into bytecode gcc does not ICE on the compile from 
the bytecode to native code but it does reject it though.

I can confirm this bug on 3.3 and it is a *real* nuisance... 
:o( 
I would vote for P1 / critical.

This was fixed by the Miranda method patch that went
in on 2003-08-11.
