Installing Oracle JDK on Windows subsystem for Linux

Question

When trying to use the Linux version of Oracle's JDK on the latest Windows 10 build having support for bash, I am running into a problem with the prompt hanging whenever attempting to invoke the java binary.

Typing even something as simple as java -version hangs and I have to terminate the process to resume control.

Anyone got this working yet?

I wanted to clarify that as of 9 December 2016, you most certainly can install Java 8 on Ubuntu Bash for Windows 10 and that @Karl Horton is correct.

You will need to install unzip sudo apt-get install unzip

Copy this script somewhere in your bash for windows session and make it executable (chmod +x filename). If you do not use a command line based editor such as vim then you will have windows line endings to deal with. you can use dos2unix or your preferred way of dealing with that. I just paste it into a file using vim.

 #!/bin/bash  set -ex  # UPDATE THESE URLs export JDK_URL=http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz export UNLIMITED_STRENGTH_URL=http://download.oracle.com/otn-pub/java/jce/8/jce_policy-8.zip  # Download Oracle Java 8 accepting the license wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" \ ${JDK_URL} # Extract the archive tar -xzvf jdk-*.tar.gz # clean up the tar rm -fr jdk-*.tar.gz # mk the jvm dir sudo mkdir -p /usr/lib/jvm # move the server jre sudo mv jdk1.8* /usr/lib/jvm/oracle_jdk8  # install unlimited strength policy wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" \ ${UNLIMITED_STRENGTH_URL} unzip jce_policy-8.zip mv UnlimitedJCEPolicyJDK8/local_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/ mv UnlimitedJCEPolicyJDK8/US_export_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/  sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/oracle_jdk8/jre/bin/java 2000 sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/oracle_jdk8/bin/javac 2000  sudo echo "export J2SDKDIR=/usr/lib/jvm/oracle_jdk8 export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin export JAVA_HOME=/usr/lib/jvm/oracle_jdk8 export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db" | sudo tee -a /etc/profile.d/oraclejdk.sh 

And now I can do the following

fieldju@DESKTOP-LTL6MIC:~$ java -version java version "1.8.0_112" Java(TM) SE Runtime Environment (build 1.8.0_112-b15) Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)                                                 

The links and versions in the above script are likely to be out of date by the time you read this, so just head over to http://www.oracle.com/technetwork/java/javase/downloads/index.html accept the license so that their js lets you copy the new URLs and you should be good to go.
