The Util-Classes project must:
<UL>
<LI>
Provide an API to ease the burden of classloading implementation
differences between JDKs.
</LI>
<LI>
Ease the effort involved in creating an SPI-like implementation.
SPI (Service Provider Interface) was first (as far as I can tell) described
in the JDK 1.3 documentation discussing the JFC input method engine in
<a href="http://java.sun.com/j2se/1.3/docs/guide/imf/overview.html">
the JDK 1.3 documentation overview of the Input Method Framework</a>,
and a description of the technology was put in <a
href="http://java.sun.com/j2se/1.3/docs/api/java/awt/im/spi/package-summary.html#package_specification">
the JavaDoc</a>.
Another implementation is needed since the Sun implementation of loading
SPI classes was privately used.
</LI>
<LI>
Helpers for creating chainable exceptions. JDK 1.4 introduces this
capability for all exceptions, but for JDK 1.1 compatible code this
is not acceptible.
</LI>
<LI>
Helpers for creating and maintaining singleton instances of classes.
