--- Comment #5 from Christopher Schultz <ch...@christopherschultz.net> --- For those curious, Java 9 introduced the invokeDynamic bytecode instruction which allows the JVM to highly optimize String concatenation operations. The "downside" is that it requires a new bytecode instruction that did not exist when your version of JDT seems to have been written.
