Source Attachment does not contain the source for the file ThreadPoolExecutor.class

问题

I am working on an android project which uses the webservice I have created. It was working fine few minutes earlier but suddenly it started to give below error.
the source attachment does not contain the source for the file threadpoolexecutor.class

Logcat error is :

I found it. I was checking the value and if everything if fine it will return null from the web service. and that null value I was trying to convert to string value and hence geting the above error.
Thanks CommonsWare.
