java.lang.OutOfMemoryError: Java heap space on Payara and Eclipse

问题

我遇到了这个错误，但很奇怪。我创建了一个Java Web应用程序，当我进行任何类型的请求时，都会出现OutOfMemory错误，但请注意，我已经让它正常工作了一个星期，直到现在都没有出现错误。（我在从一个类中获取所有对象的简单get请求中遇到了这个问题）。
以下是完整的日志：

I&#39;m getting this error but it&#39;s weird. I made a java web app and when I made any kind of request I get this OutOfMemory but keep in mind that I have this working for like a week and it does not give me errors until now. (I got this doing a simple get of all objects from a class).
This is the entire log:

I insist, it&#39;s weird because I never have this problem until now and I didn&#39;t change any line in the code.
Thanks

**得分**: 0
正如[Cristoph John]所建议的那样，这是由服务器端的限制引起的。Payara默认为512MB，而我的单例正在填充它。
我只需要进入管理控制台并进行更改。

As [Cristoph John] suggested, it was a limitation by the server side. Payara has a default 512MB and my singleton was filling it.
I just needed to go to the admin console and change that.
