OpenMRS won't start

Hello,

I have encountered almost a similar error as @darkmatter5 Link to my error: https://pastebin.com/zcEmQ4re I am using openmrs 2.1

Is Java8 still not supported?

My output for $java -version is: openjdk version “1.8.0_151” OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.16.04.2-b12) OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

I have done the complete installation and setup of openmrs with Java 8. So if I have to change my Java version, should I do the installation all over again? i.e., repeating Step 5 in https://wiki.openmrs.org/display/docs/Getting+Started+as+a+Developer
