com.google.gwt.core.client.JavaScriptException: (TypeError): Cannot call method 'indexOf' of undefined

i am trying to parse data by splitting the response string from app engine by using below code.

Resonse string: "29(0.001)"

Code:

String[] strToken = token.split("\\p{Punct}", 2);

String metricId = strToken[0];

String time = strToken[1];

double metricTime;

if (!time.contains(")")) {

metricTime = Double.parseDouble(time);

} else {

int end = time.indexOf(")");

metricTime = Double.parseDouble(time.substring(0, end));

}

its working fine in developer mode. but when i deployed to google app engine.. i am geting different exceptions in different browsers.

Chrome Exception: 

com.google.gwt.core.client.JavaScriptException: (TypeError): Cannot call method 'indexOf' of undefined
