----------------------------------------------
Summary: Installation - minimum version Java and error messages
Key: OPENMEETINGS-2389
URL: https://issues.apache.org/jira/browse/OPENMEETINGS-2389
Project: Openmeetings
Issue Type: Bug
Components: Installer
Affects Versions: 5.0.0-M4
Reporter: Sebastian Wagner
Assignee: Maxim Solodovnik
Fix For: 5.0.0
Its a bit confusing with the installer:
OpenMeetings 5.x requires Java11, but when running the startup.sh script it
will tell you first: Minimum version is 52 (which is java8) but if you try
java8 it will just not startup with:
{code:java}
07-Jun-2020 05:34:40.770 INFO [main]
org.apache.catalina.core.ApplicationContext.log No Spring
WebApplicationInitializer types detected on classpath
07-Jun-2020 05:34:40.772 SEVERE [main]
org.apache.catalina.core.StandardContext.listenerStart Error configuring
application listener of class [org.apache.openmeetings.util.OMContextListener]
java.lang.UnsupportedClassVersionError:
org/apache/openmeetings/util/OMContextListener has been compiled by a more
recent version of the Java Runtime (class file version 55.0), this version of
the Java Runtime only recognizes class file versions up to 52.0 (unable to load
class [org.apache.openmeetings.util.OMContextListener])
{code}
This could be probably be improved to just clearly make Java11 minimum
requirement.
