The problem is that the package hasn't been installed properly.

On Windows the issue is that not only JAVA_HOME must be set, but also the
Java JDK executables (javac.exe (Java compiler), jar.exe (Java archiver))
must be in the PATH. If you would have added the -verbose flag to the pkg.m
command you would have seen something like "Java:  no" somewhere in the
build messages.

So before another retry to install the Java package, add the subdirectory

%JAVA_HOME%\bin

to the PATH and try again.

FYI: this *IS* outlined on the wiki:
