-----------------------------------
Summary: Incorrect parsing of when resetting a prefix tree node
ending in LEAF_BYTE
Key: LUCENENET-531
URL: https://issues.apache.org/jira/browse/LUCENENET-531
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Contrib
Affects Versions: Lucene.Net 3.0.3
Environment: Lucene.Net.Contrib.Spatial
Reporter: John Diss
Priority: Critical
When a prefix tree node is constructed, there is an explicit check to test if
the last char is LEAF_BYTE and its presence is handled appropriately. If the
node is reused via the node.Reset method there is no such check which leads to
issues if presented with a token ending in LEAF_BYTE. This manifests as
"Unexpected char: +" in method QuadPrefixTree.QuadCell.MakeShape.
I think this happens when building a cell from e.g a rectangle shape query
parameter where the cell level is < grid depth.
