Mysterious verification error

[Erik Corry <er...@arbat.com>]

Hi

I am having a problem with a program similar to helloify
(I am hoping to use it to produce allocation and garbage
collection logs of running Java programs).

I have tried with both the 5.1 version and with the last
pre-Apache version.  The BCEL-produced class file passes
Justice verification, but fails verification by Sun with
this error message:
 
     Exception in thread "main" java.lang.ClassFormatError: HelloWorld (Field "this" has illegal signature "L<init>;")
      
The relevant files are available in
http://arbat.com/erik/verifiererror.tar.gz (5.9k)

Anyone recognise this error and what it means?

The problem only arises if I helloify the <init> method.

Yours,

Hi,

Replying to myself.

In the BCEL version of the method there is no LocalVariableTable.

I added 

    mg.stripAttributes(true);

and now it works.  According to the BCEL docs this should be 
the default, so it looks like a buglet to me.

Yours,
