First, execute a program. java -jar XXX.jar Second, In java program, run ble and run 'sudo reboot now' third, after boot, execute a program. java -jar XXX.jar

1. In case faster execute - core dump

A fatal error has been detected by the Java Runtime Environment:

2. very slowly execution - core dump or normal execution.

Q) what is the problem? linux system cause problem? or tinyB.jar cause problem? or do not close many resource in java code?
