Purpose

List of the java objects introduced/Removed by the 12.2 version of the INITJVM.SQL script. This would be considered the list of core jvm java objects owned by SYS.

Scope

This list can be used in the event that a problem occurs with a java class or set of java classes to determine whether the classes are part of the core JVM or from another source. In addition this information can be used to determine the most appropriate method of replacing the classes.

The core JVM in 12.2 should consist of approximately 40348 java objects but this value may differ slightly on different platforms and versions. The objects consist of 4 different object types as detailed below:

COUNT(*) OBJECT_TYPE
---------- -----------------------
413 JAVA DATA
1730 JAVA RESOURCE
38202 JAVA CLASS
3 JAVA SOURCE

In order to determine which object_type a particular object is the following select statement can be used:
SQL> select object_type
2 from all_objects
3 where dbms_java.longname(object_name) = '<object name>'
4 and object_type like '%JAVA%';

an example would be:
SQL> select object_type
2 from all_objects
3 where dbms_java.longname(object_name) = 'oracle/net/aso/C03'
4 and object_type like '%JAVA%';

OBJECT_TYPE
-------------------
JAVA CLASS
