h2o 构建失败，java 15

Question

h2o 版本：h2o-3.34.0.3 (rel-zizler)

Java 版本：openjdk 版本“15.0.2” 2021-01-19（安装： FROM adoptopenjdk:15-jre-openj9-focal ）

I want to build an XGBoost model using Java 15, but the same code with the same data which runs without issues on Java 14 (openjdk version "14.0.2" 2020-07-14) fails on Java 15, producing the following error messages ：

我使用以下命令启动 h2o 服务器：

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

有没有人遇到过类似的问题？ 对我来说，它看起来像是一个版本不兼容，但根据对此的评论，h2o 应该从 3.32.1.1 及更高版本支持 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已解决该问题
