I tried to make a Minecraft Server, using the suggestions I've seen people telling others to use the Paper API.我尝试使用我看到人们告诉其他人使用论文 API 的建议来制作一个 Minecraft 服务器。 So I got all the files, and I allocated 512 MB of ram to it (using -Xmx512M), and it runs completely fine, But it bumps into the limit of RAM too much.所以我得到了所有文件，并为它分配了 512 MB 的内存（使用 -Xmx512M），它运行得非常好，但是它太多地碰到了内存的限制。 so I tried to push it to 3 GB (using -Xmx3G), (A bit excessive, for what I'm using it for, but it'll help me sleep at night. knowing I have a server that's not running into issues) but then I run into the problem where Java simply does not want to start.所以我尝试将它推到 3 GB（使用 -Xmx3G），（有点过分，因为我正在使用它，但它会帮助我晚上睡觉。知道我有一个没有遇到问题的服务器）但后来我遇到了 Java 根本不想开始的问题。

I experimented a bit, found that anything higher than 1.5G and Java starts having problems.我试验了一下，发现任何高于 1.5G 和 Java 的东西都开始出现问题。 Could not reserve enough space for 3145728KB object heap .无法为 3145728KB object 堆保留足够的空间。

So I went looking around, and found people saying "Add an Environment Variable to the System Variables with _JAVA_OPTIONS and -Xmx3G" and whatever, and it appears to not change anything for me.所以我环顾四周，发现有人说“使用 _JAVA_OPTIONS 和 -Xmx3G 将环境变量添加到系统变量中”等等，这似乎对我没有任何改变。 Java still doesn't want to start. Java 还是不想入手。 Does anyone know how this is?有谁知道这是怎么回事？ I can't seem to update my Java to any higher version, assuming mine was outdated.假设我的已经过时，我似乎无法将我的 Java 更新到任何更高版本。 So it can't be an update, and not everyone runs into this issue because a server manager once told me their server ran with 10GB of ram.所以它不可能是更新，并不是每个人都会遇到这个问题，因为服务器管理员曾经告诉我他们的服务器运行 10GB 内存。

I'd ask them, but I've lost contact, so I'm asking here instead.我会问他们，但我失去了联系，所以我在这里问。
