This Error does not happen with the tomcat standalone (8080)
it happens when running tomcat + apache (i use jk12)
send to requesnt parameter just a name example in the url
and you get :

a suggested solution is to do :
if (len == 0)
   return ;
in CharChunk.java in the begining of 
public void append( char src[], int off, int len )
