Abstract
During maintenance, systems are updated to correct
faults, improve functionality, and adapt the software to
changes in its execution environment. The typical software­
update process consists of stopping the system to be up­
dated, performing the update of the code, and restarting
the system. For systems such as banking and telecommuni­
cation software, however, the cost of downtime can be pro­
hibitive. The situation is even worse for systems such as
air­traffic controllers and life­support software, for which
a shut­down is in general not an option. In those cases,
the use of some form of on­the­fly program modification is
required. In this paper, we present a new technique for dy­
namic updating of Java software. Our technique is based
on the use of proxy classes and requires no support from
