SUGGESTED FIX The problem was that _is_default_XXX was not being correctly set in the argument processing. This caused the CL option settings for these parameters to be ignored when we used the _is_default_XX test. ------- arguments.cpp ------- 1560a1561,1567 > } else if (match_option(option, "-XX:MaxNewSize", &tail)) { > _is_default_max_new_size = false; > // Back up so we can use normal argument processing > match_option(option, "-XX:", &tail); > if (!process_argument(tail, args->ignoreUnrecognized)) { > return JNI_EINVAL; > } 1571a1579,1592 > if (!process_argument(tail, args->ignoreUnrecognized)) { > return JNI_EINVAL; > } > } else if (match_option(option, "-XX:MaxTenuringThreshold", &tail)) { > _is_default_max_tenuring_threshold = false; > // Back up so we can use normal argument processing > match_option(option, "-XX:", &tail); > if (!process_argument(tail, args->ignoreUnrecognized)) { > return JNI_EINVAL; > } > } else if (match_option(option, "-XX:SurvivorRatio", &tail)) { > _is_default_survivor_ratio = false; > // Back up so we can use normal argument processing > match_option(option, "-XX:", &tail); ###@###.### 2003-06-06: fix putback to [Tiger's] gc_baseline.
