I'm not sure Sun/Oracle ever formally specified this behavior, but as a JVM
engineer since Java 0.98 I can attest to it. This behavior is also
described in JEP-280: "Currently javac translates String concatenation into
StringBuilder::append chains" (referring to Java 8).
The advantages of using St
What performance tests are define to help in determining before and after
performance improvements?

Before Java 9, javac always generated StringBuilder calls for string
concatenation (or StringBuffer prior to Java 2). Using + is less verbose,
generates the same code, is more readable, and, when we do finally bump the
compile target, will generate better code.

Thanks. In that case I'm -1 on this since it is not available in Java
8, and even in Java 9 is only possible, not necessarily implemented.
We can revisit in a few years if the JDK has moved on by then.

I presume this is referring to
https://openjdk.org/jeps/280 (JEP 280: Indify String Concatenation) which
was implemented in Java 9.

Interesting. Do you have a reference for that?

I would classify all sequences of `new StringBuilder()`, `append` and
`toString` without any branching or loops as simple cases.
Should this be enforced or can it be enforced? With Checkstyle? Som

Since the Javac compiler replaces string concatenation with
Hello serwserw...@gmail.com,
Thank you for your email.
Here are a few questions:
What passes the criteria of "simple cases"?
Should this be enforced or can it be enforced? With Checkstyle? Somethings
else?
Considering:
- that we support Java 8 and up to the current version.
- that we don't say
