The mindboggling thing is when you load a new class and those
non-virtual calls became practically virtual again, the JIT is able to
regenerate the native code, without losing the current state of all
variables and stacks.  I don't recall ever hearing of a bug in this
process.  That is more impressive than walking on water.

One of the great annoyances in programming derives from the irregularity
of English spelling especially when you have international teams.  
I want to find a method or variable, but I don't know precisely
how its is spelled or worded. English is only approximately phonetic.  
Letters are randomly doubled.  The dictionary often lists variant spellings.
British, Canadian and American spellings differ.I would like to see an 
experiment where variable names were spelled in a simplified English, where 
there were no double letters.I also think you could add a number of rules 
about composing variable names so that a variable name for something would
be highly predictable. You would also need automated enforcement of the 
rules as well as possible.
