Hash-table unavailable in compiled classes?

[tarka at internode dot on dot net (Steve Smith)]

Hi,

I've run into a problem accessing hash-tables from within compiled
classes.  I have the following scheme module:

  (module-static #t)
  (require 'hash-table)

  (define-simple-class <SchemeTest> (<java.lang.Object>)

    ((test (number :: <java.lang.String>))
     :: <java.lang.String>
     (let ((hash (make-hash-table)))
        (hash-table-set! hash 1234 (<java.lang.String>:new "1234"))
        (hash-table-ref hash 1234))))

I compile this and attempt call the method 'test' from the following
Java main class:

  import java.lang.*;

  public class JavaTest {
     public static void main(String []args)  {
         SchemeTest scm = new SchemeTest();
         System.out.println("Test run: " + scm.test("1223") + "\n");
     }
  }

I get the following:

  Exception in thread "main" java.lang.ExceptionInInitializerError
        at SchemeTest.test(test-inline.scm:6)
        at JavaTest.main(JavaTest.java:7)

        at gnu.kawa.slib.srfi69.<clinit>(srfi69.scm:60)
        ... 2 more

Is this a bug or am I doing something wrong (again)?

Cheers,
Steve
