Playing with Ubuntu 18.04. I did the builtin tomcat8 and setup Lucee war. Found out Tomcat8 in 18.04 needs openjdk 11 or throws the ByteBuffer error.
Setup 5.3.0.86 and works so far except for overview.cfm in admin. Get an error “Unable to make public long com.sun.management.internal.OperatingSystemImpl.getCommittedVirtualMemorySize()”. Noticed it is coming from GetSystemMetrics() which calls getCPU(). Don’t know if this is openjdk or Lucee. Forcing the url for other admin pages works fine.
