Provides basic information about the J2SE installation that it is run in.
JdkIntrospector will report the following system properties:
java.version,
java.home, and
sun.boot.class.path.
The values of the properties are written to standard out. Invokers can thus capture the properties by creating a new process to invoke JdkIntrospector and capturing standard out for that process.
Each property is output on its own line. The name of the property is output, followed by a tab character (0x09) and then the value of the property. After all properties have been output, a line consisting of a singl . character is output indicating the end of the data.
