JRE 8 rt.jar - com.* Package Source Code
JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries.
JRE (Java Runtime) 8 is the runtime environment included in JDK 8.
JRE 8 rt.jar libraries are divided into 6 packages:
com.* - Internal Oracle and Sun Microsystems libraries java.* - Standard Java API libraries. javax.* - Extended Java API libraries. jdk.* - JDK supporting libraries. org.* - Third party libraries. sun.* - Old libraries developed by Sun Microsystems.
JAR File Information:
Directory of C:\fyicenter\jdk-1.8.0_191\jre\lib
63,596,151 rt.jar
Here is the list of Java classes of the com.* package in JRE 1.8.0_191 rt.jar. Java source codes are also provided.

* Result is not always absolutely correct: may indicate OBJECT_HERE
* for non-existent objects, which is resolved on invocation. This
* "bug" is unavoidable, since in general the object may be destroyed
* between a locate and a request. Note that this only checks that
* the appropriate ObjectAdapter is available, not that the servant
* actually exists.
* Need to signal one of OBJECT_HERE, OBJECT_FORWARD, OBJECT_NOT_EXIST.
* @return Result is null if object is (possibly) implemented here, otherwise
* an IOR indicating objref to forward the request to.
* @exception OBJECT_NOT_EXIST is thrown if we know the object does not
* exist here, and we are not forwarding.
