我想用tomee创建一个JEE Web API。
我有一个实用的示例，但是当我尝试使用此代码启动它时
mvn clean package tomee:run
它返回此：

我试图更改Java的版本（我有9，并尝试了8，但问题相同）
openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.16.04.1-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)
我使用Ubuntu 16.04
我读到它可能是分配的内存太低。但我不知道如何解决...
如果您有任何想法？
