But any classes defined in Pascal provide those methods, if they descend

All classes on the JVM descend from a Java class. The Java Runtime does
not support classes that don't descend directly or indirectly from
java.lang.Object.
Yes, BUT: TObject is provided by the "system" unit in FPC and although it
descends from JLObject it provides basic FPC like semantics, including
free/destroy. FPC treats " TMyClass = class ..." just like it does in the
native code versions and TMyClass would descend from TObject inheriting its
methods. So unless you tried to create a class which directly descended
from JLObject, instead of TObject you inherit "free" and "destroy", so you
can call them as you usually would.
Other than missing unit functionality I've found the JVM implementation
makes Java seem very Pascal like. The devs have done a splendid job IMO. It
did take me a while to find the Java lib equivalent of StrToInt. :-D
