Re: Re: Re: Re: Re: Re: Re: Re: Release of ASM4

  ASM3 will fail to read class. With new API changes Eric and Remi are
working on you will need to make some changes in your adapters.

  Remi, it might be a good idea to write up a migration guide, i.e.
what need to be changed. If I followed your conversation right,
handling of LDC instruction and some classes been renamed.

  regards,
  Eugene
