java and javac will fork or not as described in the Manual for those tasks. As described there, they will not fork unless you use the fork attribute to turn on forking.
Using fork="false" (the default) is more efficient, but makes the execution tightly bound to your Ant environment, and doesn't allow for much customization of the JVM environment. It's impossible to set system properties for just this task, and very tricky to narrow down the classpath with fork false, for example. Scot P.
