Issue Description
JDK-8273914

Indy String Concat Changes Order of Operations


String concatenation has been changed to evaluate each argument and eagerly convert it to a string, in left-to-right order. This fixes a bug in the invokedynamic-based string concatentation strategies introduced in JEP 280.

For example, the following now prints "foofoobar", not "foobarfoobar":

` StringBuilder builder = new StringBuilder("foo"); System.err.println("" + builder + builder.append("bar")); `
