Thanks for looking at the PR and commenting.
I will take another look at the changes to `org.apache.jmeter.control` and
either revert or justify them.
I'd gladly add more tests if we move to Spock ;)
The reason for replacing `StringBuilder` with `+` is for **readability**.
That article shows, that for the simple code i.e. not building a string
inside loops etc. they are the same i.e. the JVM generates a `StringBuilder`
for the simple `+` code.
I believe they have the same performance but for me reading:
`"nodeList[" + i + "] " + nodeList.item(i)`
is much easier than:
`new StringBuilder("nodeList[").append(i).append("]
").append(nodeList.item(i)).toString()`
and
`"Row: " + row`
much easier than:
`new StringBuilder("Row: ").append(row).toString()`
My change in `InfluxdbBackendListenerClient` might be a tiny bit slower due
to the initial capacity that the JVM might use the default of 16 causing some
resizing of buffers.
Hope that makes sense.
