Abs[x] not recognized

[Former user]

I have imported the .jar files in the newest .zip file, but

DoubleEvaluator engine = new DoubleEvaluator(); engine.defineVariable("x", -1); engine.evaluate("Abs[x]");

throws me an error: org.matheclipse.parser.client.math.ArithmeticMathException: EvalDouble#evaluateFunction(FunctionNode) not possible for: Abs(x)

and engine.evaluate("Sin[x]"); does not. What could be the reason for this?
