Interface IJREVersion

All Known Implementing Classes:

DumpClassVersions

public interface IJREVersion

A constant collection to detect the current JRE version. Note that this code is more sophisticated then a mere check of "java.version" or "java.class.version" and similar system properties because some JVMs allow overriding those by the user (e.g., from the command line). This implementation relies on the core classes only and tries to minimize the number of security-sensitive methods it uses.

This interface is supported in Java 1.1+ and should be compiled with class version stamp 45.3 (-target 1.1).
