java15中的h2o构建失败

Question

h2o版本：h2o-3.40.3(rel-zzler(

Java版本：openjdk版本"；15.0.2〃；2021-01-19(安装有：FROM adoptopenjdk:15-jre-openj9-focal(

我想使用Java 15构建XGBoost模型，但在Java 14上运行的具有相同数据的相同代码(openjdk版本"14.0.2"2020-07-14(在Java 15上失败，产生以下错误消息：

我用以下命令启动h2o服务器：

ENTRYPOINT /bin/bash -c "cd h2o && java -XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -XX:MaxRAMFraction=1 -XshowSettings:vm -jar h2o.jar

有人遇到过类似的问题吗？在我看来，这是一个版本不兼容的问题，但根据本文的评论，h2o应该支持3.32.1.1及更高版本的Java 15。在R 上使用Java 16运行H2O

将Java安装更改为FROM openjdk:15.0.2-jdk-slim解决了问题
