Re: [eclipselink-users] memory leak
|
You can disable caching in EclipseLink using the persistence.xml property,
"eclipselink.cache.shared"="false"
This is a safe configuration, and recommend if caching is not desired. The
docs are referring to using a specific NoIdentityMap cache type, which is
not the correct way to disable the cache.
