Gentoo Oracle JDK on ARM
Installing a JDK on ARM has several challenges. First, there is no binary icedtea for ARM. Second, building icedtea generates circular build time dependencies.
On my first attempt, I just ran the following commands:
emerge --autounmask-write virtual/jdk
dispatch-conf
emerge virtual/jdk
dispatch-conf
emerge virtual/jdk
However, it soon met an error:

Later, when I checked on gentoo-packages, it didn’t have an arm ebuild. Oracle has hardfloat and softfloat binary JDKs for ARM, so I went on to install them. They can be used to bootstrap an icedtea build.
# emerge -av dev-java/oracle-jdk-bin

You may not have a browser installed on your ARM board, so I suggest just uploading the Oracle tarballs to a server and using wget to download them.
To fix the control panel error when you don’t have a desktop environment installed, you need to remove lines from the ebuild and digest it.
vim /usr/portage/dev-java/oracle-jdk-bin/oracle-jdk-bin-1.7.0.40.ebuild
These lines need to be removed:
newicon jre/lib/desktop/icons/hicolor/48x48/apps/sun-jcontrol.png \
sun-jcontrol-${PN}-${SLOT}.png || die
sed -e "s#Name=.*#Name=Java Control Panel for Oracle JDK ${SLOT}#" \
-e "s#Exec=.*#Exec=/opt/${P}/jre/bin/jcontrol#" \
-e "s#Icon=.*#Icon=sun-jcontrol-${PN}-${SLOT}#" \
-e "s#Application;##" \
-e "/Encoding/d" \
jre/lib/desktop/applications/sun_java.desktop \
> "${T}"/jcontrol-${PN}-${SLOT}.desktop || die
domenu "${T}"/jcontrol-${PN}-${SLOT}.desktop
sun-jcontrol-${PN}-${SLOT}.png || die
sed -e "s#Name=.*#Name=Java Control Panel for Oracle JDK ${SLOT}#" \
-e "s#Exec=.*#Exec=/opt/${P}/jre/bin/jcontrol#" \
-e "s#Icon=.*#Icon=sun-jcontrol-${PN}-${SLOT}#" \
-e "s#Application;##" \
-e "/Encoding/d" \
jre/lib/desktop/applications/sun_java.desktop \
> "${T}"/jcontrol-${PN}-${SLOT}.desktop || die
domenu "${T}"/jcontrol-${PN}-${SLOT}.desktop
Once removed, generate the manifest for it.
ebuild /usr/portage/dev-java/oracle-jdk-bin/oracle-jdk-bin-1.7.0.40.ebuild digest
If you run emerge dev-java/oracle-jdk-bin, it will succeed.
