Subject [jira] [Commented] (DERBY-6809) Java 1.8 feature use

------------------------------

Hi Rick, 
Thanks.

>From your reply,Dunno how a particular code executes only if a platform is available (implementation)...
any links to src file of the same in derby codebase ... should get me started ...

Though again java8 src is blackbox to me ... obviously its not possible that java8 provides
increased parallelism to the java6 codebase transparently ... unless they have some artificial
intelligence in the JIT and Runtime which detects such candidate bytecode and does it on the
fly ... AFAIAC ... thats not what it is ...

Yes am interested in performing some experiments very much but need someone (help) to point
me to a particular piece of code or  two or 3 source files ... yes low hanging fruit discovery
will get the Java8 and future track started ... since its a huge huge task to convert the
code manually to java8

So looking for some one to point to an implementation in src somewhere that uses collections
sorting loop etc. which then can be converted and then tested against a query on both the
default derby and the derby8 on jvm8.

I still feel that even a 1% chance of 5% improvement in performance is worth taking since
now the software (JVM) supports the hardware commonly available ... 

Thanks, 

Sagar

>    Affects Versions: 11.0.0.0

> Suggestion ...
> Is it possible to auto modify the existing source code using tools like Netbeans, and
take advantage of the new features in JDK 1.8 for better multiuser performance and better
utilization of current day multicore processors?
> Plainly put, can we have from 11.0 onwards a version of derby which takes advantage of
the advancements and new features in java 1.8 ...
