Unwrap does nothing. What’s wrong?

Please check the Logging Page in the Logging window. One of the following error messages is expected:

  • Could not unwrap this code. Most probably it was not wrapped with the Oracle 10g, 11g or 12c wrap utility.
  • SHA-1 hash values do not match. Expected ‘…’  but got ‘…’. Cannot unwrap code.

If you’ve got the latter message, the wrapped code has most probably been modified.
