Are you getting  [1] again? That means there there is a empty line in your
siddhi.extension file. In the SiddhiExtensionLoader class, the relevant log
line is as follows:

log.error("Cannot load Siddhi extension " + className);

So, the class name should be printed. The class name is not printed since
its empty.

[1]. ERROR - {SiddhiExtensionLoader}  Cannot load Siddhi extension
