6.4. What Are All These "_g" Versions?

One thing you will notice right away when you unpack the IBM Java SDK is that it has virtually all of the same commands as does the Sun Java SDK, but there is a whole bunch of them duplicated with a mysterious "_g" suffix. What's up with that?

These versions run a Java VM that was compiled with debug information, so that you can report information about bugs and errors that is of use to IBM SDK developers in locating and fixing problems. These versions should not be used for production work, but only to recreate and report bugs.
