Subject: CFV: new hsx committer: David Chase

I hereby nominate David Chase (OpenJDK user name: drchase) to HSX Committer.

Since November of 2012, David has contributed widely to the HotSpot code
base.

Here are his commits, more recent first:

8002160: Compilation issue with adlc using latest SunStudio compilers
8014959: assert(Compile::current()->live_nodes() < (uint)MaxNodeLimit)
failed: Live Node limit exceeded limit

About four credit him (as david.r.chase) in a "Contributed-by" line; the
others are under his username.

The gross volume of contributions is 9100 lines of patch, comprising 1500
lines deleted and 2900 added, touching about 150 files.

The change sets for 8014013, 7088419, and 6443505 are especially complex and
subtle, while 7104565 is a large change to the makefile system.

David's experience includes optimizing compilers, JVM implementations, and
parallel systems, at Oracle Labs, Sun, NaturalBridge, and Thinking Machines.

Votes are due by Tuesday, October 15.

Only current hsx Committers [1] are eligible to vote on this nomination.
