A DESCRIPTION OF THE PROBLEM :
My application is running under linux box, and I was tring to replace the windows file seperator with a solaris/linux file seperator for a path String,

Code likes:
String serverPath = tempPath.replaceAll("\\",File.separator);

I got exception:

java.util.regex.PatternSyntaxException: Unexpected internal error near index 1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
String tempPath = "\\root\\temp";

String serverPath = tempPath.replaceAll("\\",File.separator);


EXPECTED VERSUS ACTUAL BEHAVIOR :
no exception caught and serverPath = "/root/temp" as expected.
I got exception:
