Hmm no, the version is openjdk 1.8.0_171-8u171-b11-0ubuntu0.16.04.1-b11 which is 8 as far as I understand. Anyway, I switched away from OpenJDK and using plain JDK is working fine :)

Hi, I just updated my Ubuntu desktop where I run the openmeetings server and I think that the updated Java VM is not supported by red5: Exception in thread "main" java.lang.UnsupportedClassVersionError: org/red5/server/Bootstrap : Unsupported major.minor version 52.0 Maybe downgrade it? -- WBR Maxim aka solomax
