No and yes. No because not testing immutability is the same as making it mutable, which is what you're doing anyway.
Yes, because testing immutability is the standard pattern that should be followed. @Dynamic causes it to pass. I guess the advantage of this approach is if good style is used and all fields are declared together, it's easy to see which are mutable.

Set/get methods implemented :-)
Will put @Dynamic. Even if I put this tag, do I need to still test immutability in the setter?

Be sure to use get/setCheckCharacterPortability() in FileCacheLoaderConfig as the primary mechanism for storing/retrieving this property. Make the field @Dynamic, as there is no reason this can't be changed on a running cache.

1) I'm adding a switch in the properties section. I think default value should be true having the possibility to switch it off by setting "check.character.portability" property to false.
2) done

Hey Galder,
Couple thoughts on the validation stuff in FileCacheLoader:
1) How about adding an on/off switch to FileCacheLoaderConfig? If I know my stuff conforms, I don't want to pay the performance penalty to check it.
2) I believe Pattern is thread safe, so you should be able to cache your compiled patterns in a static field.

Perf tuning for JBoss Cache
by Manik Surtani
Guys,
Every time we see or suspect potential inefficiencies in the JBoss
Cache codebase (stuff we spot while working on other features or
debugging stuff) we should note these down so they can be revisited
later.
At some point I do want to do a full performance analysis as well,
but for the time being this could be useful to capture stuff we see
as we go along.

Valdiations in FileCacheLoader
by Brian Stansberry
Hey Galder,
Couple thoughts on the validation stuff in FileCacheLoader:
1) How about adding an on/off switch to FileCacheLoaderConfig? If I know
my stuff conforms, I don't want to pay the performance penalty to check
it.
2) I believe Pattern is thread safe, so you should be able to cache your
compiled patterns in a static field.

JBCACHE-867
by Elias Ross
I finished most of getting rid of the TreeCacheProxyImpl references. It took
more time than anticipated.
All said, it was about 1800 lines of adds and 2000 lines of removes.
TreeNode and DataNode are pretty empty. There's now a NodeSPI which might
need some work, but it's pretty pleasant. I also refactored out a lot of
lock stuff into something that hangs off of NodeSPI.
Some tests may have been messed up (buddy replication and the move feature
and probably some others) and I haven't had time to figure these complicated
ones out. I hope this doesn't upset anybody. If somebody could help fix
these, that would be great.
I would like to suggest the following things:
1. Cache should not implement Node, it's confusing when reading an
implementation of Cache
2. Node sould include useful methods of TreeNode, such as getChild(Object)
and getName()
3. Cache should have a getCacheSPI()
4. CacheSPI should not extend Cache
5. Cache needs move(), not Node. The reason is clear if you see NodeImpl.
In the current design, CacheSPI has to have all the methods of Cache. Why
couldn't CacheSPI be written as a separate object? (It could, but then you
would just have to delegate ...)
