I thinkI found it in task RMIC:
Path classpath = getCompileClasspath(baseDir);
loader = new AntClassLoader(project, classpath);
try {
String classname = ....
Class testClass = loader.loadClass(classname);
// One cannot RMIC an interface
if (testClass.isInterface() ||
!isValidRmiRemote(testClass)) {
return null;
}
} catch (ClassNotFoundException e) {
log("Unable to verify class " + classname +
". It could not be found.", Project.MSG_WARN);
} catch (NoClassDefFoundError e) {
log("Unable to verify class " + classname +
". It is not defined.", Project.MSG_WARN);
}
