Java 9/jigsaw slides

[Karen Kinnear]

Folks,

Brian recommended that I speak at the Philly Emerging Tech conference and they 
would like a talk about
Java 9, with some hints of future plans.

Do any of you have slides you would recommend that I could use as a starter set?

thanks,
Karen

Re: RFR: 8171855: Move package name transformations during module bootstrap into VM

[Karen Kinnear]

Claes,

Thank you for all the good work you are doing identifying performance issues 
and making improvements.

I strongly agree with Lois’  concerns.

We looked at other cases in which we have an interface from java to the VM that 
need to
pass fully qualified names, e.g. Class.forName(). The model used there might be 
useful
to you as an alternative way to get the same performance benefits.

see Class.c - which uses some existing libjava utilities to do the conversion.

So this has the benefit of not creating extra java strings, while keeping the 
JVM interface consistent.
It also reduces the risk of missing locations.

We are happy to have further discussions offline if you like.

If you think this is a more general issue, and want to revisit JVM APIs, then 
we can look at that
in a future release, in which we will have time to consistently modify the 
model, and create common
utilities.

thanks,
Karen

Re: RFR: Proposed jimage refresh for JDK9

[Karen Kinnear]

Folks,

We have concerns with the current jimage design relative to the JVM interfaces. 
We need to investigate alternative approaches here,
including a libjimage.so analogous to libzip.so that would be called directly 
from both the JDK and the jvm. Some have suggested having most of the logic
be in java. We are concerned about checking in JVM_* interfaces that will 
should go away soon and concerned about licensees and other java vendors
adopting them making them harder to remove the longer they are there.

Jim has explained that it is critical to get these changes in quickly so that 
the IDEs can get the updated jrtfs APIs, and that it is a huge amount
of work to decouple the API changes from the jimage changes or to make the 
requested jimage interface changes.

Assuming it is critical for these changes to go into JDK9 immediately rather 
than fixing the design issues first -
We propose adding the JVM_* interfaces as deprecated when they go in.
We would like commitment from Jim and those setting priorities for the jimage 
work that the changed design and JVM_* interfaces will be in the next
set of changes coming from his team.

If this is a problem due to priorities or staffing, can you please talk to us 
about that now?

thanks,
Karen

 I have a cunning plan.  However, getting this jimage refresh in play has me 
 really bogged down (there is always one more thing -- curse you Jobs.)
 
 I do plan on moving the bulk of the jimage JVM_ calls to the JDK. The 
 callbacks into the VM will be reduced to a few calls (open, close, read, 
 read_compressed) and will be VM style correct.
 
 Cheers,

 Okay although JVM_* functions have never been a supported interface (to my 
 knowledge anyway).
 
 These are the current rules, which assume that even though unsupported, 
 these interfaces are known to our customers and licensees.
 
 
 Also I think we need to see where this is going longer term, my 
 preference would be to move these JVM_* functions out of the VM and put 
 the jimage support in its own libjimage.so. I realize this requires mmap 
 and other support that might be tied a bit to VM options but I think we 
 should at least explore it.
 
 I think this functionality should be in Java.
 We might be talking different issues here, I assume you need a minimal 
 native implementation to startup.
 
 Yes.  It seems wasteful to have the JDK code call back to the JVM for this, 
 and then we have new JVM functions to support (and have to file CCC requests 
 if we remove them).
 
 Thanks,
 Coleen
