Deadlock while creating a Coordinate Reference System
-----------------------------------------------------
Key: GEOT-1368
URL: http://jira.codehaus.org/browse/GEOT-1368
Project: GeoTools
Issue Type: Bug
Components: core referencing
Affects Versions: 2.3.2, 2.0.0
Reporter: Urs Reupke
Assignee: Martin Desruisseaux
Attachments: CrsCreationDeadlock.java, CrsCreationDeadlockJUnit.java
The FactoryFinder's method to retrieve an CRSAuthorityFactory and the
CRSAuthorityFactory's method to create the coordinate reference system (CRS)
deadlock each other if run in a multithreaded environment, like a web server.
I have attached both a java executable and a JUnit4 test case to document the
problem. Both should log their actions 10 times in a row and then exit, stating
that no deadlock was encountered, but they stop running inbetween.
The test demonstrates the erroneous behaviour in both GeoTools 2.0 and 2.3.2.
The problem can be worked around by synchronizing the calling method, but I'd
be glad if this could be fixed directly in GeoTools.
