Can trigger infinite loop in StreamingRenderer.processStylers
-------------------------------------------------------------
Key: GEOT-2049
URL: http://jira.codehaus.org/browse/GEOT-2049
Project: GeoTools
Issue Type: Bug
Affects Versions: 2.5-RC0, 2.4.4
Environment: RHEL3, Java 1.6.0_07, JBoss 4.0.3SP1, GeoServer 1.6.4
Reporter: Ryan Hofschneider
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.
See partial stack trace below:
