  This behaviour may be by design.
  
  According to the pipeline step reference, httpRequest: Perform an HTTP Request and return a response object takes a parameter:
  
  
  
  	
  responseHandle (optional)
  How response should be handled.
  STRING(default) will transform the response in string.
  NONE will not read the response content and will close the response after the job execution.
  LEAVE_OPEN will not read the response content but leaves an open input stream to be read outside the job execution. Using LEAVE_OPEN it is your responsibility to close it after use. 'response.close();'
  	
  
  		
  Values: NONE, LEAVE_OPEN, STRING
  	
  	
  
  
  
  and Java strings are UTF-16; so, if you don't want the plugin to recode the response body to UTF-16, then you should specify a value different from STRING for the responseHandle parameter.
  
  If the pipeline indeed requires the responseHandle step to return a string, then I don't think the MAX_LENGTH limit can be fixed in the plugin.
