# jre_option

Passes command line options to the JVM at start-up.

    jre_option = JVMoption

The `jre_optio`n parameter can be used to define Java system properties, which are used by applications running in the JVM, such as extensible security modules.

You can use multiple `jre_option` entries in order to pass more than one options to the JVM. Permitted values for JVMoption include most JVM options that are defined by Sun Microsystems.

For example, this restricts the maximum heap size of the JVM to 256 megabytes:

    jre_option = -Xmx256m
