Method and apparatus for dynamically selecting bytecodes for just in time compiling in a user's environment

A process in a computer for executing a set of instructions, wherein the instructions are nonspecific to the computer and are for use with a virtual machine, the process comprising the computer implemented steps of:

• presenting compiling information for a set of instructions on an output device;
• receiving user input changing the compiling information for the set of instructions, wherein updated compiling information is formed;
• monitoring for a call to compile the set of instructions;
• responsive to detecting the call, determining, based on the updated compiling information, whether the instructions should be compiled into native code specific for the computer;
• and
• responsive to a determination that the set of instructions should be compiled, sending the set of instructions to a compiler designed to generate native code specific for the computer.

An application execution system for use in a computer comprising:

• a virtual machine, wherein the virtual machine receives a set of bytecodes for the execution;
• a compiler, wherein the compiler generates native code specific for execution by the computer from bytecodes;
• a graphical user interface, wherein the graphical user interface included has a number of modes of operation including:
• a first mode of operation in which the graphical user interface displays compiling options for a plurality set of bytecodes;
• a second mode of operation in which the graphical user interface receives input altering the compiling options;
• a third mode of operation, responsive to receiving the input altering the compiling options, in which the graphical user interface saves the input altering the compiling options;
• and
• an interface, wherein the interface includes a number of modes of operation including:
• a fourth mode of operation in which the interface monitors for a call to compile a set of bytecodes from the virtual machine;
• a fifth mode of operation, responsive to detecting the call to compile the method in the first mode of operation, in which the interface determines, based on the compiling options, whether the set of bytecodes should be compiled;
• and
• a sixth mode of operation, responsive to a determination that the set of bytecodes is to be compiled, sending the set of bytecodes to the compiler.

A data processing system in a computer for selectively just in time compiling a method, the data processing system comprising the computer implemented steps of:

• presenting means for presenting compiling options for the method on an output device;
• receiving means for receiving user input changing the compiling options for the method;
• monitoring means for monitoring for a call to just in time compile the method;
• determining means, responsive to detecting the call to just in time compile the method, for determining, based on the compiling options, whether the method should be compiled;
• and
• sending means, responsive to a determination that the method is to be compiled, for sending the method to a just in time compiler.

A data processing system in a computer for executing a set of instructions, wherein the instructions nonspecific to the computer are for use with a virtual machine, the process comprising the computer implemented steps of:

• presenting means for presenting compiling information for a set of instructions on an output device;
• receiving means for receiving user input changing the compiling information for the set of instructions, wherein updated compiling information is substituted for the compiling information;
• monitoring means for monitoring a call to compile the set of instructions;
• determining means, responsive to detecting the call, for determining, based on the updated compiling information, whether the instructions should be compiled into native code specific for the computer;
• and
• sending means, responsive to a determination that the set of instructions should be compiled, for sending the set of instructions to a compiler designed to generate native code specific for the computer.

A computer program product in a computer readable medium for selectively just in time compiling a method, the computer program product comprising:

• first instructions for presenting compiling options for the method on an output device;
• second instructions for receiving user input changing the compiling options for the method;
• third instructions for monitoring a call to just in time compile the method;

• and
• fifth instructions, responsive to a determination that the method is to be compiled, for sending the method to a just in time compiler.
