无法在JDk13上运行dacapo基准测试

Question

我正在尝试从这里(https://github.com/dacapobench/dacapobench)运行daCapo基准测试。

我给了JAVA_HOME作为export JAVA_HOME="/home/srcshetty/Desktop/ALL_JDKs/jdk-13.0.1/"

我已经安装了构建基准所需的所有依赖项。

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

当我使用JDK12及更低版本时，它能成功运行，而当我使用JDK13时，它就不能工作了。

使用JDK13时，我得到了以下错误消息。

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，构建成功，并且我也成功地运行了基准测试。但是使用JDK13时，我得到了上面的错误，但我无法找出。

Lucene build使用了编译器(-Xdoclint)的doclint特性，看起来在JDK13中变得更加严格。标志在lucene/common-build.xml... -Djavac.doclint.args=""中设置。
