Hi,
It was just brought to my attention that the output of java -version is
different on builds of jdk8 when compared to jdk7 [1]:
# java -version
openjdk version "1.8.0-internal"
OpenJDK Runtime Environment (build 1.8.0-internal-0)
OpenJDK 64-Bit Zero VM (build 25.0-b20-internal, interpreted mode)
# java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (fedora-2.3.10.3.fc19-ppc64)
OpenJDK 64-Bit Zero VM (build 23.7-b01, interpreted mode)
OpenJDK 7 identifies itself as "java version...." while OpenJDK 8
identifies itself as "openjdk version...". Is this intentional? Will
this be changed after Java 8 is finalized?
It comes from common/autoconf/version-numbers which has:
LAUNCHER_NAME=openjdk
which seems to be a mistake to me as obviously the launcher name is
not openjdk.
This was introduced to differentiate between an openjdk build vs. Oracle's
jdk build (with closed). There used to be some make magic which deciphers
what to set.
I thought all Java versions claimed "java version #.#.#_#", including
those from other proprietary vendors.
Also, the lines after "java version" make OpenJDK explicit, no? Is this
second line not sufficient to distinguish OpenJDK vs closed builds?
# java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (fedora-2.3.10.3.fc19-ppc64) <--- this line
OpenJDK 64-Bit Zero VM (build 23.7-b01, interpreted mode)
we needed to account for java -fullversion as well, which btw. is a one
liner.
It was decided the OpenJDK launcher name to be openjdk as well, there
were discussions of course surounding this, but I can't remember.

Thanks,
