java - 无法在 JDK13 上运行 dacapo 基准测试

Question

我正在尝试运行此处提供的 daCapo 基准测试 ( https://github.com/dacapobench/dacapobench )。

我将 JAVA_HOME 设置为 export JAVA_HOME="/home/srcshetty/Desktop/ALL_JDKs/jdk-13.0.1/"

我已经安装了构建基准测试所需的所有依赖项。

我通过在 benchmark 文件夹中运行 ant lusearch 来测试 lusearch 基准测试。

当我使用JDK12及以下版本时可以成功运行，而当我使用JDK13时则无法运行。

我在 JDK13 中收到以下错误消息。

当我使用 JDK12 运行时，我必须将源代码从 1.5 更改为 1.7 或更高版本，并且构建成功，并且我也成功运行了基准测试。但使用 JDK13 时，出现上述错误，我无法弄清楚。

Lucene 构建使用编译器的 doclint 功能 (-Xdoclint)，看起来它在 JDK 13 中变得更加严格。标志在 lucene/common-build.xml 中设置...-Djavac.doclint.args=""。
