/**
|
|
* The StrictfpInSource annotation marks whether or not the element in
|
|
* source was declared strictp in its source form. For release 16 (and
|
|
* earlier releases), the strictfp-in-source status and
|
|
* strictfp-in-class file status should generally match. (Per JLS,
|
|
* some elements are implicitly strictfp).
|
|
*
|
|
* Under release 17 and later releases reflecting JEP 306, while
|
|
* strictfp can be present in the source, it is *not* persisted to the
|
|
* class file for methods/constructors where ACC_STRICT can be
|
|
* applied. (The ACC_STRICT modifier is not defined for
|
|
* classes/interfaces in the JVM.)
|
|
*
|
|
* This test checks that the strictfp modifier of the annotated
|
|
* elements is as expected in the four combinations:
|
|
*
|
|
* (source, class file) X (--release 16, current release)
|
|
*
|
|
* As well as the mixed combination of -source 16 and current release
|
|
* as the implicit target.
