This is a virtual machine. I am thinking this problem because of the memory is not big enough. If some one agree with me.
这是一个虚拟机。我在想这个问题是因为内存不够大。如果有人同意我的看法。

Try
尝试
java -Xmx64m
Basically your machine doesn't have enough memory, but you may be able to get away with 64MB. Let me know how you get on.
基本上你的机器没有足够的内存，但你可能能够逃脱 64MB。让我知道你是怎么办的。

You can use this command to know your current memory usage:
您可以使用此命令来了解您当前的内存使用情况：
swapinfo -tam
I had the same error and the memory use was above 95%.
我有同样的错误，内存使用率高于 95%。
