JDK 9 Early Access with Project Jigsaw, build 135 on 09-14-2016 (#5500)

[Alan Bateman]

The EA download [1] has been refreshed with new builds that are mostly 
aligned with the current proposals for JPMS issues [2]. Not everything 
is there yet of course (and some areas need a few more iterations) but 
there is enough to test and try things out.

For #ReflectiveAccessToNonExportedTypes and #AwkwardStrongEncapsulation 
then the initial support for `weak module` and `exports private` is in 
place. These are probably the highest priority changes to try out.

The changes to setAccessible in #AwkwardStrongEncapsulation is going to 
be disruptive and will no doubt expose hacks in many areas. We've run 
into several of these already. The command line option to allow existing 
code to break into non-public types/members is --add-exports-private. 
The format of the value passed to this option is the same--add-exports. 
With #AddExportsInManifest then there are equivalents in the application 
JAR main manifest to try out too.

As part of the #ClassLoaderNames then the format of the stack trace 
elements has changed.

For #ServiceLoaderEnhancements then the implementation is mostly 
aligned, except for the static factory method which needs an update to 
javac and SL to align with the proposal (should be there soon, just not 
in this build).

Several people have brought up #ResourceEncapsulation and 
#ClassFilesAsResources here so it would be good to try this out.

As always, the most valuable feedback is from those trying out the 
builds so please let us know what you have tried and what works or 
doesn't work.
