Deadlock in while updating feature using WFS

Issue Type:

BugBug

Affects Versions:

2.2-beta2

Assignee:

Andrea Aime

Components:

WFS

Created:

18/Jun/12 5:49 AM

Description:

There is a dedlock in GeoServer when Transaction and DescribeFeatureType operations are executed concurrently.
It can be reproduced with QuantumGIS (1.7.4) and WFS plugin.
Just try to update any feature attribute. It semms that while Transaction request is being submitted, QuantumGIS sends DescribeFeatureType which causes everything to lock. Actually it may be QuantumGIS problem, but it causes GeoServer to stop serving another WFS requests.
