Uses reflection to build a valid hash code from the fields of {@code object}.
</p>
<p>
This constructor uses two hard coded choices for the constants needed to build a hash code.
</p>
<p>
It uses <code>AccessibleObject.setAccessible</code> to gain access to private fields. This means that it will
throw a security exception if run under a security manager, if the permissions are not set up correctly. It is
also not as efficient as testing explicitly.
</p>
<P>
If the TestTransients parameter is set to <code>true</code>, transient members will be tested, otherwise they
are ignored, as they are likely derived fields, and not part of the value of the <code>Object</code>.
</p>
<p>
Static fields will not be tested. Superclass fields will be included. If no fields are found to include
in the hash code, the result of this method will be constant.
</p>
@param object
