I am using JCS 2.2. I am an infrequent user of JCS, so please bear with
me. I have checked the mail list archives for past few years, couldn't
find any answers to this q...
I have a cache region whose key type is say String and whose value type
is some class C. C is Serializable.
I use the cache, so objects of class C go into that region. The cache is
backed by disk, so objects of class C end up in files.
C may then change, such that its serialVersionUID changes. If so, what I
want to happen is that when I do a
C c = cache.get( "K" );
I would like to see the InvalidClassException, so that I can call
cache.clear()
and start over with the 'new' C objects.
But cache.get() doesn't throw such an error. I always get a null result
back, which means I can't distinguish this type of error from a simple
cache miss (key not present), so I can't call the cache.clear().
Somewhere in the call stack, JCS is catching the error so that it
doesn't propogate to user code?
Are there any api calls I can make to set the cache up so that it is
cleared on this type of error?
Thanks
Stu
