Can trigger infinite loop in StreamingRenderer.processStylers
-------------------------------------------------------------
Key: GEOS-2244
URL: http://jira.codehaus.org/browse/GEOS-2244
Project: GeoServer
Issue Type: Bug
Components: WMS
Affects Versions: 1.7.0-RC3, 1.6.4
Environment: RHEL3, Java 1.6.0_07, JBoss 4.0.3SP1, GeoServer 1.6.4
Reporter: Ryan Hofschneider
Assignee: Andrea Aime
Priority: Critical
org.geotools.renderer.liteStreamingRenderer.processStylers() iterates over a
FeatureReader using FeatureReaderIterator within a while loop.
If the hasNext() method of the FeatureReaderIterator (e.g. JDBCFeatureReader,
as in the stack trace below) throws an exception, the exception is caught
within the while loop, the loop starts again, the exception is thrown and
caught again, and so forth until the JMV is killed or the log file fills the
available disk space.
For relevant portion of stack trace see:
http://jira.codehaus.org/browse/GEOT-2049
Discovered this issue when GeoServer created a 60GB log, logging a stack trace
every few milliseconds.
Perhaps coincidentally, the stack trace is very similar to the one described in
this thread:
http://www.nabble.com/max-features-tt18590812.html
The request that triggered this infinite loop is very similar to the one
described in that thread as well.
