sagar commented on DERBY-6809:
------------------------------

Ok. So a safe place to start. The sort package has ample use of Vectors.

Knut, any example where exactly the replacement was made just as a reference.

True, there could not be a major measurable improvement by replacing the Vector 
in a mergesort but as you said, I still am unable to read the mind of the 
original programmer of this code as to why a Vector (synchronized datatype) was 
used in the first place.



> Java 1.8 feature use

> 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 ...
