Title: Java Client Code

Describe the issue:
https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Data_Grid/6.1/html-single/Developer_Guide/index.html#Java_Client_Code1

There is an extra invalid character "\" in the "Get a String Value from a Cache" example code:

    while ((line = bufferedReader.readLine()) \!= null) {

Suggestions for improvement:
Remove the \

Additional information:
Do we not at least check to make sure the examples compile before including them in the documentation?
