Descriptions

In Eclipse OpenJ9, prior to the 0.12.0 release, the jio_snprintf() and jio_vsnprintf() native methods ignored the length parameter. This affects existing APIs that called the functions to exceed the allocated buffer. This functions were not directly callable by non-native user code.

En Eclipse OpenJ9, en versiones anteriores a la 0.12.0, los métodos nativos jio_snprintf() y jio_vsnprintf() ignoraban el parámetro length. Esto afecta a las API existentes que llamaban a las funciones para sobrepasar el búfer asignado. Estas funciones no eran llamables directamente por el código de usuario no nativo.
