Java compilation error messages

Question

Is there any way for HTML DB to return error messages during Java compilation? Every create java command I submit -- unless there is a grievous syntax error -- seems to return statement processed:
Given....
CREATE OR REPLACE FUNCTION returnOne
   RETURN NUMBER
AS LANGUAGE JAVA
   NAME 'JavaTest.returnOne ()
            return int';Test #1 -- a valid Java source code:
create or replace java source named "JavaTest" as
public class JavaTest
  public static int returnOne()
       return 1;
Statement processed.
0.20 seconds
begin
  htp.p(returnOne());
end;
1
Statement processed.
0.11 secondsTest #2 -- Invalid source code -- there is no indication until runtime that anything is wrong:
create or replace java source named "JavaTest" as
public class JavaTest
  public static int returnOne()
       iCalendar ical   = new iCalendar();
       return 1;
Statement processed.
0.18 seconds
begin
  htp.p(returnOne());
end;
ORA-29541: class ARDB.JavaTest could not be resolved
0.37 seconds               :(

Answer 1

Er....yeah....but do you have any idea why the SQL Command Processor would not return any errors when trying to compile a class with a non-valid dependency?
Another example:
create or replace and compile java source named "JavaTest" as
public class JavaTest
  public static int returnOne()
       MyFooBarClass ns = new MyFooBarClass();
       return 1;
Statement processed.
