我正试图为jee wildfly应用程序进行单元和跨学校测试。在测试执行期间，我发现堆栈溢出。我试图增加记忆，但没有成功。在我看来，它在创建包时看起来像是oom，但我不确定。
你能帮忙吗？我也想生成jacoco覆盖。我正在使用wildfly 10。

PS： 在jenkins奴隶上看到使用的memeory只有1G
system monitor performance tab
仍有问题：
嗨，我知道增加记忆力并不能解决问题。内存不足不是问题的原因。现在我需要6GB RAM，我有47％的代码覆盖率。因此，如果内存将增加线性，我将需要12GB的空闲RAM来测试我的40MB（带库和图片）应用程序。我认为这有点不对劲。它看起来像内存泄漏。
在arquillian + jacoco配置中有如此大的内存消耗是否正常？
