Review comment:
       What do you mean, how does it impact debugging? E.g. not being able to 
put a breakpoint there? I don't think we should optimize for that in the source 
code - less verbose is usually better. Plus for debugging purposes, you can 
always stop at the return line and evaluate the boolean expression in your IDE, 
or just see what which branch the execution follows after 
`isConnectionException()`.
