At the moment, in Eclipse IDE, users can add any JRE to a
project's build path, regardless of the JRE that the IDE is
running on.
For e.g. users can have multiple installations/versions of JRE 8
in different projects and each of them will be considered a
different platform
library because they are coming from different path/location. Same
goes for multiple versions of JRE 9. And all this while running on
a JRE 7
or JRE 8 or a different installation of JRE 9 for e.g.
This basically means that, (with our current framework) we are
going to be able to read classes (code) from a given .jimage
location/path or java.home.
We would like to keep it that way, if possible. I remember seeing
your response [1] to one of the questions earlier but not sure if
that is meant to work for JRE 7.
I did a quick search and this one [2] looks relevant too.
As things currently stand then the IDE can run on JDK 8 and load the jrt
file system provider from the target JDK 9. It's also possible to run on
JDK 9 and access the classes/resources in that run-time image.
JDK-8066177 will make it possible to run on JDK 9 and access the
classes/resources in another JDK 9 or JDK 10 build. It's not there yet
but is on the list. Previous prototypes on this ran into issues with
shadowing of lambda proxy classes that need further investigation There
is also a bit of refactoring needed to take account of work in JEP 260.
So I can't say when all this will be in JDK 9, we know of course that
this is important.
Note that JDK 7 is not in this picture, this project is not planning to
include a jrt-fs.jar in JDK 9 builds that is usable by JDK 7.
