Hi,

can somebody explain to me what does the following exception mean?
Code:
Caused by: org.hibernate.cache.CacheException: net.sf.ehcache.CacheException: java.lang.RuntimeException: Failed to instantiate ManagementServer.

Hello,
It means that the Management Server, the code that provides a REST API for management and monitoring of your cache managers, found more than 1 file named META-INF/services/net.sf.ehcache.management.ManagementServer in your application classpath - and it's not supposed to happen (it uses underneath a ServiceLoader that determines whether to use the OpenSOurce or Enterprise code)

in a nutshell, it means you have classpath issues : I'd say you have several ehcache jars in your classpath.

If you could list all the jars found in your classpath, and if you provided the version of ehcache embedded, we could help you some more.

And if you are not interested in the Rest API for management and monitoring, you can simply disable it and happily forget this message : in your ehcache.xml :
<managementRESTService enabled="false"/> below your <ehcache ..> tag
