Digression

The subject really must be in Latin, n’est pas? While I have no formal instruction in Latin, I should
come up with one — what with Latin’s
pretty formal structure, my general understanding
of syntax and “feel” for languages, my finishing a Natural Language Processing (6.863J) incomplete 10 years later, Vocabula computatralia,
Mike McLarnon’s conjugation applet
and Verbix…

Should it be “Quis emendabit ipsos emendatra”?

I should probably asked someone to translate it, which reminds me of a
recursive acknowledgment Littlewood
describes in
A Mathematician’s Miscellany. He talks about a translated paper that had three end-notes at the end of it:

1. I wish to thank NN for translating this article
   
2. I wish to thank NN for translating the above note
   
3. I wish to thank NN for translating the above note

And that, of course, where it ends, for, though the author did not know the
target language, he was perfectly capable of writing note #3: by copying the second note…

So, to start with, I decided to go with JDB. First question is, how
best to use it in development:

• 
  Getting JDB to work with my own JPDA connector asked on forum
  on Sun’s Developer Network
  

• Getting JDB to work with my own JPDA connector asked
  on comp.lang.java.help

Then came home and figured out that I have to:

• put
  tools.jar from the JRE’s home (as different
  from JAVA_HOME, which, apparently, is assumed to be
  JRE’s home — to wit, if you have JDK installed, it’s, e.g.,
  D:jdk1.5.0jre rather than D:jdk1.5.0). In other
  words, dropping the tools.jar into the jre/lib/ext
  folder in addition to it's righteous place in
  <JDK_INSTALL_DIR>lib did the trick...
  

• You should properly override name() of the Connector you're
  implementing correctly for diagnostic (so that you're not confused by
  the output of jdb -listconnectors) but that's a minor thing...
