Exception logging.

At some point in my code hibernate sometimes throws an LazyInitializationException. This is perfectly reasonable because the session is not always available. Because this is not really a problem I catch the exception and log a simple warning in my logfile or just ignore the case and continue.

Something like this:

Code:

try {
  List<User> user = group.getUsers();
} catch (LazyInitializationException e) {
  // ignore
}

Because I catch this exception and consider it to be harmless (within my code) I don't want my logfiles spoiled with useless stacktraces. Although I catch it and ignore it, Hibernate still logs the stacktraces which is really annoyng:

Code:

...
INFO: building session factory
Sep 9, 2006 3:19:34 PM org.hibernate.impl.SessionFactoryObjectFactory addInstance
INFO: Not binding factory to JNDI, no JNDI name configured
Sep 9, 2006 3:19:34 PM org.hibernate.LazyInitializationException <init>
SEVERE: illegal access to loading collection
org.hibernate.LazyInitializationException: illegal access to loading collection
   at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:341)
   at org.hibernate.collection.AbstractPersistentCollection.read(AbstractPersistentCollection.java:86)
   at org.hibernate.collection.AbstractPersistentCollection.readElementExistence(AbstractPersistentCollection.java:142)
...

Does anyone know why hibernate dumps stacktraces of exceptions that could possibly be catched later?

LIE is definitly not something to ignore...and that is also a reason to why we log it to be able to always see it even with users try/catch/ignore constructs.

turn off logging for that particular calss in hibernate

like

level.org.hibernate.... = off

but as said above LIE is one of the most important exceptions that hibernate throws ..not to be ignored

Ignoring or not ignoring exceptions has nothing todo with the type of exception. It depends primarilly on the logic of the context in which it is thrown/caught.

Thaks for the replies anyway.
