Thanks for contributing an answer to Stack Overflow! At the same time, you should realize that the JLS string concatenation spec allows JVM implementations to optimize away the autoboxing, provided the result is the same, so your JVM may instead use a StringBuilder, or use any other valid JVM bytecode to create the resulting string, so the performance of the string concatenation operator is often better than performing boxing yourself would be. referencedColumnName elements must be specified in each such However, if you try to convert a value .

I personally think ranking types in this fashion was a bad idea, since it means that code like long l = getSomeValue(); float f=l; double d=f; will compile cleanly without a squawk despite a severe loss of precision compared with storing l directly to d; it has some other unfortunate consequences as well.
