Strange indeed
Anyway, while I don't believe that's your issue I just wanted to point out
that the code below proves nothing:
> Log.error("classloaders: " + other.getClass.getClassLoader.
eq(None.getClass.getClassLoader)) // true
. . . since it will always be 'true'
I believe your were trying to see if matching key's class was loaded by the
same class loader as matcher class, so you have to compare the ClassLoader
of the actual type of the key vs None, other etc.
For example:
val v1 = new Foo
val v2 = new URLClassLoader(Array[URL](new URL("file:///foo/bar/foo.jar")),
null).loadClass("Foo").newInstance();
val map = Map(v1 -> "", v2 -> "");
map.keys.foreach{
key => println(key.getClass.getClassLoader())
}
Cheers
