Hi,

I also have these files, and every other arch user with
java-environment-common and/or java-runtime-common installed.

/usr/bin/schemagen -> /usr/lib/jvm/default/bin/schemagen
/usr/bin/tnameserv -> /usr/lib/jvm/default-runtime/bin/tnameserv
/usr/bin/rmid -> /usr/lib/jvm/default-runtime/bin/rmid
/usr/bin/javah -> /usr/lib/jvm/default/bin/javah
/usr/bin/xjc -> /usr/lib/jvm/default/bin/xjc
/usr/bin/rmic -> /usr/lib/jvm/default/bin/rmic
/usr/bin/unpack200 -> /usr/lib/jvm/default-runtime/bin/unpack200
/usr/bin/servertool -> /usr/lib/jvm/default-runtime/bin/servertool
/usr/bin/wsimport -> /usr/lib/jvm/default/bin/wsimport
/usr/bin/wsgen -> /usr/lib/jvm/default/bin/wsgen
/usr/bin/pack200 -> /usr/lib/jvm/default-runtime/bin/pack200
/usr/bin/orbd -> /usr/lib/jvm/default-runtime/bin/orbd

(all broken symlinks in /usr/bin, /bin links to /usr/bin)

In the PKGBUILD for the pkgbase java-common [1] we find

package_java-runtime-common () {
...
  # Official list of binaries that Java headless runtime packages MUST provide
  # This list is based on Arch Linux' default Java implementation: "OpenJDK 7 Icedtea"
  for b in \
    java keytool orbd pack200 rmid rmiregistry servertool tnameserv unpack200;
  do
    ln -s /usr/lib/jvm/default-runtime/bin/${b} "${pkgdir}/usr/bin/${b}"
  done
}

and

package_java-environment-common() {
...
  install -d "${pkgdir}/usr/bin"
  # Official list of supplementary binaries that Java environment packages MUST provide
  # This list is based on Arch Linux' default Java implementation: "OpenJDK 7 Icedtea"
  for b in \
    jar jarsigner javac javadoc javah javap jcmd \
    jconsole jdb jinfo jmap jps jstack jstat \
    jstatd rmic schemagen serialver wsgen wsimport xjc;
  do
    ln -s /usr/lib/jvm/default/bin/${b} "${pkgdir}/usr/bin/${b}"
  done
}

so it seems these binaries are mandatory for java 7.

What I find more curious is that no package from the repos provides
these binaries, pacman -F does not return anything for any of these packages.
My guess is that these files were available in the removed java 7 package.

And looking it up in the archive [2] proved my guess true,
/usr/lib/jvm/java-7-openjdk/bin/schemagen
was available in jdk7-openjdk.

(note that /usr/lib/jvm/default is also just a symlink)

I conclude that java-common seems to be outdated :)

Best regards
