Loading fails, when classes from other packages are referenced

Question

My applet follows a simple package structure.
There's package P1 and there's another package in it P2 (P1.P2)
P1 contains Applet class A.
P2 contains another class C and interface I. C implements I.
A contains a reference of C, which is initialized in the constructor. The use in the constructor of the A (the applet) is something like this
public A () {
          reg = ToolkitRegistry.getEntry (); //where reg is a reference of type ToolkitRegistry.
          // some more code
          i = (I) C.getC (); //where i is a reference of type I.
}Trying to load this applet throws error saying "Package Loading failed". Important is to note that the loading occurs successfully by commenting out this line           i = (I) C.getC (); //where i is a reference of type I. , without any other change.
I understood this to be some problem with the AIDs assigned to both the packages while converting. Unsure of what's the correct way to assign the PIX values, I've been trying some permutation/combinations, it doesn't seem to work.
Has neone already faced this problem & knows the solution? (The specs aren't much help)

Answer 1

One more point ..... I mentioned commenting the statements, I DO NOT commment the other statements referencing the other package. This means that the loading IS succesfull, even when these two lines reside in there.
1. import P1.P2.*; 2. private I i = null;Above two lines pass the loader. The object creation gets stuck.
Wonder if the package references are actually alright, because JVM wud've treated both situations in a similar way. JCVM is ofcourse different but JCVM spec does not say nething abt this situation (rem: everything is public, so the access control restrictions also do not apply)
are there ne instantiation restrictions? [In my case, it's in the constructor thread)
