Hi Pranavan, You have a new line as the last line of the siddhi.extension file. The SiddhiExtensionLoader class uses BufferedReader#readLine method to read the custom extension lines in the file. Therefore, the final line is read as another empty line by the Extension Loader, and then tries to load that extension using Class#forName() method. That is the reason for this error. Can you remove the empty line at the end of the siddhi.extension and try again?
