Dianne/anyone,
i would like to elaborate on the shared jar's memory model.
my understanding is that:
a. the code (read only) segment of the shared jar resides in common
memory => code will be loaded once regardless of the number of
apps
using the shared jar
b. the data (read/write) segment of the shared jar is part of the
calling
process'es address space => all static data (blocks, constructors
etc.)
will be initialized _separately_ for each app using the shared
jar
are my assumptions correct?
