This distribution can sometimes be used to diagram Java programs by running
them.  For this to work, you must have the Sun SDK installed.  That SDK must
have a tools.jar, which must be in the classpath when you use
UML::Sequence::JavaSeq.  Further, the classpath must also include Seq.java
found in the java directory of the distribution.  See README
and samples/README for details.

During testing, I will try to find your SDK and its tools.jar, which I
will temporarily insert into the classpath.  If I can't do that, I will
skip the Java tests.
