It now compiles Classpath out of the (CVS) box for me. Great.

I would not take the gcj verifiers to seriously. That code needs a bit
more love (and testcases) before I would trust it (but Tom did fix the
last bug I found yesterday, yeah Tom!). And my little VerifyClass
program does a couple of wacky things which you should not do with
ClassLoaders. But I have attached what I have found with the gcj
--syntax-only and the libgcj verifier.
And this time it actually had a valid VerifyError!
This new jikes is a bit to clever about String concatenations.
Take the following from javax/naming/RefAddr.java:
public String toString()
{
return "[RefAddr type: "+getType()+" content: "+getContent()+']';
}
This gives a: java.lang.VerifyError: verification failed at PC 30 in
javax.naming.RefAddr:toString(()Ljava.lang.String;): incompatible type
on stack
Which is correct since the byte code reads:
Method name:"toString" public Signature: 10=()java.lang.String
Attribute "Code", length:61, max_stack:3, max_locals:1, code_length:37
0: new #35=<Class java.lang.StringBuffer>
3: dup
4: ldc #37=<String "[RefAddr type: ">
6: invokespecial #42=<Method java.lang.StringBuffer.<init>
(java.lang.String)void>
9: aload_0
10: invokevirtual #20=<Method javax.naming.RefAddr.getType
()java.lang.String>
13: invokevirtual #46=<Method java.lang.StringBuffer.append
(java.lang.String)java.lang.StringBuffer>
16: ldc #47=<String " content: ">
18: invokevirtual #46=<Method java.lang.StringBuffer.append
(java.lang.String)java.lang.StringBuffer>
21: aload_0
22: invokevirtual #27=<Method javax.naming.RefAddr.getContent
()java.lang.Object>
25: invokevirtual #51=<Method java.lang.StringBuffer.append
(java.lang.Object)java.lang.StringBuffer>
28: ldc #52=<String "]">
30: invokevirtual #56=<Method java.lang.StringBuffer.append
(char)java.lang.StringBuffer>
33: invokevirtual #58=<Method java.lang.StringBuffer.toString
()java.lang.String>
36: areturn
It is trying to call append(char) on the String "]". Note that the java
source has a char ']'. Jikes seems to have decided to promote it to a
String. jikes 1.15 did not do this.
The rest of the verify output follows, but I have not analysed it yet.
But the above error seems like a showstopper.
Cheers,
Mark
