java.lang.ClassCastException throwed by
org.geoserver.config.util.XStreamPersister while saving a layer with
"java.lang.Short" bondary values
---------------------------------------------------------------------------------------------------------------------------------------------
Key: GEOS-3701
URL: http://jira.codehaus.org/browse/GEOS-3701
Project: GeoServer
Issue Type: Bug
Components: Configuration
Affects Versions: 2.0.0
Environment: Windows Vista x64. Sun Java Development Kit 1.6.0 Update
16 32 bits + JAI for Windows x86 32 bits + JBoss Application Server 4.2.3.
Geoserver 2.0.0 Web War Version.
Reporter: Rodolfo Rothganger
Assignee: Justin Deoliveira
Fix For: 2.0.1
While tring to register a layer mapped to a GeoTopp 30 data store (bounded to
-60, -60, -20, -10) with SRS EPSG:4326), the following error is generated:
java.lang.ClassException: cannot convert java.lang.Short to java.lang.Double
I´ve mapped the problem to the following lines of codes on class
"org.geoserver.config.util.XStreamPersister" (lines 957 to 972):
if ( Double.isInfinite(
((Double)range.getMinValue()).doubleValue() ) ) {
context.convertAnother( "-inf" );
}
else {
context.convertAnother( range.getMinValue() );
}
writer.endNode();
writer.startNode("max");
if ( Double.isInfinite( ((Double)range.getMaxValue()).doubleValue()
)) {
context.convertAnother( "inf");
}
else {
context.convertAnother( range.getMaxValue() );
}
writer.endNode();
Fixed the problem with the code change bellow:
if ( Double.isInfinite( ((Number)range.getMinValue()).doubleValue() ) ) {
context.convertAnother( "-inf" );
}
else {
context.convertAnother( range.getMinValue() );
}
writer.endNode();
writer.startNode("max");
if ( Double.isInfinite( ((Number)range.getMaxValue()).doubleValue()
)) {
context.convertAnother( "inf");
}
else {
context.convertAnother( range.getMaxValue() );
}
writer.endNode();
Although the change worked, I am not sure that is the best fix. I believe
somechanges related to the use of Generics on the class NumberRange (and not
the raw type) would solve the problem. Perhaps on line 954, something like:
NumberRange<? extends Number> range = NumberRange(? extends Number) original.
