Hi Remi,
I recompiled the Fib program against the latest mlvm, and then reran
the program with backport using the same command:
$ java -javaagent:backport/jsr292-backport.jar -cp .:target/classes
g7.tests.classgen.Fib
and I got this exception (at least it seems that JIT trasformation of
the backport was trying to do something):
methodInfo map {$indy_stub2$=INDY_INVOKE:delegate(invoke class
java.lang.Object fib[class java.lang.Object]),
$indy_stub1$=INDY_INVOKE:delegate(invoke class java.lang.Integer
minus[class java.lang.Integer, class java.lang.Integer]),
$indy_stub0$=INDY_INVOKE:delegate(invoke class java.lang.Boolean
__lt__[class java.lang.Integer, class java.lang.Integer])}
Exception in thread "main" java.lang.VerifyError
