Class JavaEnvironment

java.lang.Object
org.apache.shiro.util.JavaEnvironment
@Deprecated public abstract class JavaEnvironment extends Object
Deprecated.
This class is no longer used in Shiro and will be removed in the next major version.
Internal helper class used to find the Java/JDK version that Shiro is operating within, to allow for automatically adapting to the present platform's capabilities.

Note that Shiro does not support 1.2 or earlier JVMs - only 1.3 and later.

This class was borrowed and heavily based upon a nearly identical version found in the Spring Framework, with minor modifications. The original author names and copyright (Apache 2.0) has been left in place. A special thanks to Rod Johnson, Juergen Hoeller, and Rick Evans for making this available.

Since:
0.2
