Instrumented subclass of an abstract subclass of a logical class throw InstantiationError

• Severity:

  3 Feature failure (but usable), workaround available
• Fix In Branch:

  trunk
• Terracotta Target:

  Pending

abstract class A extends HashSet;
class B extends A

If B is included for instrumentation, you'll be rewarded with a java.lang.InstantiationError

Some actual sample code that produces the issue:

private static abstract class AbstractSub extends HashSet { public abstract String abstractMethod(); }

private static class SubclassOfAbstractLogicalSubclass extends AbstractSub {
final String s = "sdkfj";

public String abstractMethod() { return s; }
}
