因此，我在服务器上运行java -version并得到：
Picked up _JAVA_OPTIONS: -Xmx256M
Error occurred during initialization of VM
Could not reserve enough space for code cache
我已经尝试通过执行以下操作来增加内存堆大小：
export _JAVA_OPTIONS="-Xmx4098M"
仍然出现相同的错误：
Picked up _JAVA_OPTIONS: -Xmx4098M
Error occurred during initialization of VM

仍然出现相同的错误。
