Missing boxing conversion for boolean

ExtendJ 8.0.1-235-g49efefa Java SE 8

The bytecode generated for this test is not executable:

public class N5 {

  public static void main(String[] args) {
    boolean b = true;
    Boolean boxed = b;
    System.out.println(boxed);
  }
}

Expected result: should print "true"

Actual result: stack map induced verification error:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:
