Abstract

"SISTEMA E PROCESSO PARA EXECUTAR CóDIGO DE PROGRAMA, E, SUPORTE TANGìVEL PORTADOR DE UM PROGRAMA DE COMPUTADOR PARA REALIZAR O DITO PROCESSO". Uma máquina virtual Java (2), compreende uma máquina de execução para executar código de bytes Java e um sistema de gerenciamento de memória (14). O sistema de gerenciamento de memória (14) efetua a coleta de lixo para remover objetos que são inalcançáveis pelo estado atual do programa Java. No sistema de gerenciamento de memória anteriormente existente objetos representando uma definição de classe são somente removidos da memória se o objeto do carregador de classe que carregou o objeto classe é inalcançável. De acordo com a presente invenção o sistema de gerenciamento de memória (14) é previsto para remover classes que não possuam quaisquer objetos instanciados que possam ser alcançados no presente estado do programa se o carregador de classe ainda é alcançável. Isto resulta em uma substancial economia de memória. De preferência os objetos representando uma definição de classe tem um processo que pode sinalizar para isto que a definição pode ser removida da memória se não tem mais quaisquer objetos instanciados.
