Segfault detected, aborting process. Use runtime option -R:-InstallSegfaultHandler if you don't want to use SubstrateSegfaultHandler.
解决办法
根据报错信息可以看到最终是因为调用connect.close方法导致得，而这个方法最终又调用了org.sqlite.core.DB#free_functions而free_functions方法是一个native方法，作用是删除用户定义函数使用的内存，猜测是在释放内存得时候地址计算错误或者是什么原因导致。具体原因不清楚有知道的大佬还请指教，我们最后解决办法是：
1. 更换纯java数据库hypersql
2. 继续使用sqlite数据库，但是不调用close方法
