The first error is nothing to worry about. The cache
is falsely detecting an error.
At the end of the update method in the LRUMemory cache
was this check:
if ( map.size() != dumpCacheSize() )
{
log.error( "update: After spool,
size mismatch: map.size() = " + map.size() + ", linked
list size = "
+ dumpCacheSize() );
}
It was outside the synchronized block, so it could
return incorect values. As you see, the two values
are the same in the log, but they must have been
different at the conditional. I moved the check into
the synchronized block and changed the error to a
warn.
I'm synchronizing all the public methods in the Sorted
pref array.
This shouldn't effect the performance in any noticable
way. I'm doing more testing on this change.
