1.1.6 BigDecimal mystery: "AssertionError: NULL Metaclass!?!?!-"

This code:

wrapper = new RubyBigDecimal(runtime, (BigDecimal)obj);

produces this error in 1.1.6 but not 1.1.4:

-java.lang.AssertionError: NULL Metaclass!!?!?!-
org.jruby.RubyBasicObject.(RubyBasicObject.java:193)
org.jruby.RubyObject.(RubyObject.java:95)
org.jruby.RubyNumeric.(RubyNumeric.java:100)
org.jruby.RubyBigDecimal.(RubyBigDecimal.java:142)
ed.lang.ruby.RubyObjectWrapper.toRuby(RubyObjectWrapper.java:115)

What am I doing wrong?

I was not loading the bigdecimal library in my Java code. To lazily
load it when needed, I created the following static method:

/**
 * Creates a RubyBigDecimal from a Java BigDecimal. Lazily loads the 

Ruby
* BigDecimal class when first needed.
*/
public static RubyBigDecimal javaBigDecimalToRubyBigDecimal(Ruby
runtime, BigDecimal bd) {
if (runtime.fastGetClass(“BigDecimal”) == null) // lazily load
runtime.getLoadService().require(“bigdecimal”);
return new RubyBigDecimal(runtime, bd);
}
