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.

/**
 * The Holder for <tt>Fixed</tt>.  For more information on
 * Holder files, see <a href="doc-files/generatedfiles.html#holder">
 * "Generated Files: Holder Files"</a>.<P>
 * FixedHolder is a container class for values of IDL type "fixed",
 * which is mapped to the Java class java.math.BigDecimal.
 * It is usually used to store "out" and "inout" IDL method parameters.
 * If an IDL method signature has a fixed as an "out" or "inout" parameter,
 * the programmer must pass an instance of FixedHolder as the corresponding
 * parameter in the method invocation; for "inout" parameters, the programmer
 * must also fill the "in" value to be sent to the server.
 * Before the method invocation returns, the ORB will fill in the contained
 * value corresponding to the "out" value returned from the server.
