MIP SDK Java Wrapper示例程序随机崩溃并生成核心转储

环境与问题概述 #

• 基于MIPSDK-File-Java-Basic示例程序，使用MIP SDK Java Wrapper 1.12.101版本解密AIP保护的Office文件
• 运行环境：Ubuntu 20.04虚拟机、RHEL 8镜像
• 现象：部分文件可成功解密，但程序随机崩溃并生成核心转储，无固定触发频率——有时启动后立即崩溃，有时解密上百个文件后才崩溃

疑问与求助 #

• 不确定上述错误指向，需要排查建议
• libmip_file_sdk.so来自微软官网下载的mip_sdk_file_rhel8_1.12.101.tar.gz，崩溃是否由MIP SDK本身导致？
