我正在尝试在虚拟内存限制为 2GB 的环境中使用 java，ulimit -v 2000000但出现内存错误。java -version在此环境中运行会给出：
$ 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.
不管我设置得有多低-Xmx，我都无法让java在这个环境下运行。但是，如果ulimit -v设置为2.5GB，那么我可以设置-Xmx为250m，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
#
# There is insufficient memory for the Java Runtime Environment to continue.

java version "1.7.0_19"

是否可以在使用ulimit限制虚拟内存的环境中使用java？
