JustIce problem with

I trying to use the JustIce with 1.5 classes but i get this error

Operand of LDC or LDC_W must be one of CONSTANT_Integer, CONSTANT_Float or
CONSTANT_String, but is 'CONSTANT_Class[7](name_index = 214)'.

I have search and this seems to be the reason
JVM spec has changed so that LDC/LDC_W can load CONSTANT_Class constants - those
instructions are issued by the 1.5 compiler now, when you use a class literal. 
So it seems that it must be added to the options
At Pass3aVerifier
public void visitLDC(LDC o){
indexValid(o, o.getIndex());
Constant c = cpg.getConstant(o.getIndex());
if (! ( (c instanceof ConstantInteger)	||
	(c instanceof ConstantFloat) 		||
(c instanceof ConstantString) ) ){
constraintViolated(o, "Operand of LDC or LDC_W must be one of CONSTANT_Integer,
CONSTANT_Float or CONSTANT_String, but is '"+c+"'.");
			}
		}

As you can see the ConstantClass was not added
