Question

我们在WebLogic 12c和Red Hat OS上运行了一个Web应用程序，可访问单个SQLite数据库文件。对于此数据库，我们使用com.mchange.v2.c3p0.ComboPooledDataSource配置了连接池。在Web应用程序的客户端执行非特定的操作时，突然发生WebLogic崩溃，并且JVM会生成核心转储文件。

进行一些研究，我想这可能是SQLite使用本机库并尝试加载它们然后发生错误。这可以在JVM生成的日志文件中看到。

我想这也有帮助：

以下是日志文件中指定的线程：

Current thread (0x00007fc6240f5000):  JavaThread "C3P0PooledConnectionPoolManager[identityToken->1bqyqw79hrvpgj518gc0n4|4f77bcba]-HelperThread-#0" daemon [_thread_in_native, id=47441, stack(0x00007fc6678ff000,0x00007fc667a00000)]

我不确定这是否是问题，如果是，我不知道如何修复它。可能导致这种情况的任何想法？

此外，我们正在使用JDK 1.8.0-77以及这些依赖于pom.xml
