java 10.0.2+13 throws a java.lang.module.InvalidModuleDescriptorException when a module-info.class in a directory in the module path exports a package that isn't under the same directory.
That is sensible behavior in many circumstances, but, in my case, I have the package under another directory which is patched into the module in question using --patch-module.
Example:
Module m is defined in file classes/m/module-info.class.
m exports package p.
module-info.class is the only child of directory classes/m.
Directory classes/patch contains p/Main.class.
Simplified command line:
java --module-path classes/m --patch-module m=classes/patch --module m/p.Main
The above will throw a java.lang.module.InvalidModuleDescriptorException that says that "Package p not found in module".
Is there any way to get java to not throw an InvalidModuleDescriptorException, without having to copy the class files from classes/m & classes/patch into the same directory, or into the same jar file?
