Description

When a disk store sized in bytes is topped by a caching tier sized in entries and the latter one ends up creating an inverted pyramid, the disk store inline eviction fails to free the {{DiskMarker}}. Guilty code is in {{net.sf.ehcache.store.disk.Segment#faultInternal}} in the block {{if (incomingDiskSize < 0) {}}.

See this [discussion

https://groups.google.com/forum/#!category-topic/ehcache-users/ehcache-core/Vq7kJPghkpE] which discovered the problem and which contains a test which exhibits the problem as long as the onheap size is changed to be between 191 and 1000.

The fix for this was committed back in May, forgot to update the issue status.
