ECJ and Java 9
Hi,
Does anyone have info on Java 9 support in ECJ ? This is going to be needed
for JSP support (obviously). I tested 4.7Ms [good news: it's a drop in
replacement for our current 4.5] but there's no change in that area.

The CompilerOptions.VERSION constants are just strings, the static field
could probably be replaced by "1.9" and/or "9" to preserve the
compatibility during the transition.

I tested this beta build, but I don't see much difference yet. It still
cannot access the base module classes it seems (errors like:
"java.lang.Throwable cannot be resolved to a type", that cannot be normal).
Also, there's an issue with the Java 9 constant that is used in Tomcat,
CompilerOptions.VERSION_1_9 -> CompilerOptions.VERSION_9. This creates a
compatibility problem where the new vs old build cannot be drop in
replacements.

There is a Java 9 branch in the Git repository, I don't know how much
of the new features it supports though:
http://git.eclipse.org/c/jdt/eclipse.jdt.core.git/log/?h=BETA_JAVA9
It looks like the beta builds have a tag starting with Y, this one is
the latest available:
http://git.eclipse.org/c/jdt/eclipse.jdt.core.git/snapshot/Y20160929-1000.tar.gz
