determined that the interpretation of a method meets certain criteria that indicate a hot spot, then
the interpretation is halted. A new method is then constructed, compiled, and invoked in such a
manner that the newly constructed method recreates the execution state of the halted method.
(specification, page 5) The compiled method executes at a faster speed than the interpreted
method. (specification, page 38, lines 25-27)
Claim 1 is representative of the claimed invention and is reproduced as follows:
1. A process for executing a method, the process comprising the computer-implemented
steps of:
during execution of an interpreted method, determining to compile the interpreted
method;
constructing a second method;
compiling the second method; and
invoking the second method so that an execution state of the interpreted method is
recreated.
