Re: Using Lomboz plugin with Eclipse

What other solutions did you experiment with? In particular, I'd like to
know what you tried that didn't work.

I ask because classes.jar is already in the boot-classpath, so creating a
symlink to it is superfluous if the lomboz plugin is using its contents.

If the plugin is just looking for the presence of a file, then any file
should satisfy it, and a symlink is overkill.

If the plugin is looking for a jar, then any jar should work, and using the
smallest jar possible would consume less resources in the JVM. It takes
time and memory to keep a JarFile open.

In any case, reopening classes.jar to load classes from it should be either
pointless or mistaken, if I understand ClassLoaders correctly.

As far as I can tell, none of the classes contained in the reopened
classes.jar will ever be loaded by a well-behaved classloader.
Classloaders, I believe, are supposed to ask their parent classloader for
any class first, and only if that fails to return a Class should they look
for the class in their own source of classes. Since every class in the
symlinked classes.jar is already in the boot-classpath, hence loaded by the
bootstrap classloader, no class will ever be loaded from the reopened
classes.jar. Iff I understand classloaders correctly.
