No. Imagine you are writing a class that needs to run on Java 5 but are using JDK 6 as your
compiler. If you use the compilers default class path then you run the risk of introducing
methods/classes into the Java5 code that are only in JDK 6.

It's just like when there was a jdk13 classpath property even though a jdk 1.4 compiler was
required.
