Need reviewers and comments:
6989472: Provide simple jdk identification information in the
install image
http://cr.openjdk.java.net/~ohair/openjdk7/jdk_release/webrev/
With JDK6 Updates we purposely resisted many rebranding changes that
could impacted
customers, however at one point we had accidently changed the Windows
DLL/EXE
COMPANY value thinking that no one would be looking at it.
We were wrong and this change cause Eclipse failures, so we are
looking for a solution, see:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=321390
So we went back and change JDK6 Updates back the way it was, and
learned a valuable lesson.
But we have and will change JDK7 in this regard, so we wanted a better
way for an app to
know what it had it's hands on without using platform specific
information in the binary files.
The above change creates a small text file called "jdk.release" at the
top of the install image
with some basic values that could help direct any app using the jdk in
constructing a command
line or even being assured that this jdk install image will even work
on your existing system.
In the Eclipse case it was looking for "Sun", but I suspect it really
wanted to know if the VM was
"Hotspot" because I think it was trying to set a Hotspot specific
PermGen option.
In any case I think this jdk.release file should provide the necessary
answers in the future.
The make variable COMPANY_NAME determines the vendor name during a
build,
so a Linux 64bit build from a make command line like:
make COMPANY_NAME="Test Company Name"
should result in a jdk.release file that looks something like:
os.name = Linux
os.version = 2.6
os.arch = amd64
java.vendor = Test Company Name
java.version = 1.7.0-internal
java.vm.vendor = Test Company Name
java.vm.name = Hotspot(TM)
java.vm.version = 20.0-b02
A formal Oracle jdk7 EA build on Linux 64bit should look something like:
os.name = Linux
os.version = 2.6
os.arch = amd64
java.vendor = Oracle Corporation
java.version = 1.7.0-ea
java.vm.vendor = Oracle Corporation
java.vm.name = Hotspot(TM)
java.vm.version = 20.0-b02
Comments are welcome. Although, polite constructive comments are
probably more what I'd like to see. ;^)
