Objet: Re: JDK 9 Jigsaw builds
actually, I think I did see somewhere that JDK9 will support only 8 and
7 as targets. Maybe someone can confirm that.
not at all !
It's not the JDK, it's just javac.
ups, yes, I did mean javac.
javac only support 4 releases, it's not something new, i think that policy was introduced with javac 7,
to be able to remove old code. So javac 9 support 9, 8, 7, and 6. And for the last supported platform, javac emits a warning.
4, ok, I had something like the current plus the last two in mind. Seems I did remember wrong and seems like we then can still go with 1.6 as target level then.
so on my laptop,
$ /usr/jdk/jdk-9/bin/javac -source 1.5 Foo.java
warning: [options] bootstrap class path not set in conjunction with -source 1.5
error: Source option 1.5 is no longer supported. Use 1.6 or later.
$ /usr/jdk/jdk-9/bin/javac -source 1.6 Foo.java
warning: [options] bootstrap class path not set in conjunction with -source 1.6
warning: [options] source value 1.6 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
I see, thanks.
