我们有 3 个 clover 数据库，一个用于客户端测试、集成测试和单元测试。
为了计算总覆盖率，我们将这些数据库合并到一个新的三叶草数据库中：如您所见，这按预期工作（并且现在已经超过 18 个月了）

自上周末以来，我在尝试从合并的 coveragedb 文件生成报告时遇到以下问题：

[clover-report] Report generation failed: Clover encountered a problem reading the instrumentation registry "d:\coverage\java\all\clover\cloverDB\coverage.db". This database may have been corrupted. Please regenerate.
我检查了文件并注意到它的大小（根据 Windows 资源管理器）：2,08 GB（2.244.583.202 字节），刚刚超过 2GB。我不知道前几个周末运行的大小，因为我们不保留覆盖 dbs，但由于程序中没有其他任何更改，我认为 2GB 是这里的问题。
