Re: When will JDK 9 builds move to requiring the boot JDK be JDK 8?

[Fredrik Öhrström]

You are right Kelly, the old build system did use the idlj from the boot
jdk.

The new build, does build a bootstrap idlj, as can be seen here:
he
http://hg.openjdk.java.net/jdk9/jdk9/corba/file/14e7fbdd1dcb/make/GensrcCorba.gmk

And uses this bootstrap idlj to compile the idl files, so at least that odd
boot jdk dependency is removed.

Re: When will JDK 9 builds move to requiring the boot JDK be JDK 8?

[Kelly O'Hair]

As I recall, corba builds do some code generation with idlj, which is in corba 
I think, so a boot jdk version of idlj
would need to be built and run with the boot jdk, then you could build 
everything with the new jdk.
Or so I recall..

If we're cross-compiling, the JDK being built may never be executable


But the code in the jdk repository in JDK N is built such that it can 
use the language features and new libraries of JDK N. In contrast, the 
code in the corba (and IIRC jaxp and jaxws) repo is restricted to using 
features in the boot JDK, typically JDK (N-1).

As I understand it, the new build compiles the repositories in this 
order so that it matches the old build. In previous mails about this 
here then it was suggested that this would be re-examined in JDK 9. Once 
we get JDK 9 building as modules then this issue should go away too as 
code would no longer be compiled a repository as time as it does now.

Re: When will JDK 9 builds move to requiring the boot JDK be JDK 8?

[Mike Duigou]

The general plan had been to wait until Java 8 was final before switching from 
JDK 7 to JDK 8. We planned switch internal Oracle build systems to JDK 8 after 
the April 15th CPU release. However, since there seems to already be a mix of 
JDK 7 and JDK 8 in use it is probably appropriate to switch now.

Re: When will JDK 9 builds move to requiring the boot JDK be JDK 8?

[Erik Joelsson]

As Chris pointed out, we have a patch that's already been reviewed, so 
making the change is trivial. I do think a bit of a heads up to jdk9-dev 
is a good idea though.

there isn't a JDK 8 available is sufficient?

Which properties need changing David ? We should list them.

The strange thing here is that JPRT is already using JDK 8 (b132) as

Yes, I changed JPRT a while back since we "should" already be using JDK 
N-1 as boot. Changing configure to disallow JDK 7 is a different change. 
I think the only thing that really held us back was JDK 8 being properly 
released.

Agreed. The link above is a RFR from Erik to not accept JDK 7 as a bootstrap. 
It was sent out back in Dec last year.

I know but I also replied suggesting that he hold off pending a 
conclusion on the boot JDK issue. If this is pushed then it's the third 
patch in last 24 hours to allow corba build with different versions of 
7uX as the boot JDK. I think would be be better to just get the switch
