现象
debug启动后，过段时间就非正常退出；添加jvm参数-XX:+CreateMinidumpOnCrash后，保存堆转存日志；
之前debug启动，但从未出现此问题；不知为何，突然就出现这个问题了；
错误信息

Current thread (0x000000000a428800): JavaThread “JDWP Transport Listener: dt_socket” daemon [_thread_in_vm, id=5632, stack(0x000000000b440000,0x000000000b840000)]

注意到Current thread信息，current thread就是出问题的thread，百度发现JDWP Transport Listener 是debug的程序。
实验发现，debug启动后，过段时间就会非正常退出；正常启动，不会存在这个问题。
解决办法
临时只能非debug启动了。
