我试图在虚拟内存被ulimit -v 2000000限制为2GB的环境中使用java，但是我遇到了内存错误。在此环境中运行java -version会产生：
$ java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
无论我设置-Xmx有多低，我都无法在这种环境下运行java。但是，如果ulimit -v设置为2.5GB，那么我可以将-Xmx设置为250米，但不能更高。
$ java -Xmx250m -version
java version "1.7.0_19"
OpenJDK Runtime Environment (rhel-2.3.9.1.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
$ java -Xmx251m -version

是否可以在使用ulimit限制虚拟内存的环境中使用java？
