Hi,
We have used camel 1.1 for our project and wanted to upgrade to 1.2 (We were
missing the @Headers Tag in 1.1).
But we found a bug in the try - catch handler: I the catch block is a
pipline, the pipline (in the catch block) detects that the exchange has
failed and aborts the catch handler. :(
I've worte a simple unit test to demonstrate this:
public class TestTryCatch {
public class MyBean {
public void process( Object obj ) {
if( obj instanceof Integer )
Logger.getLogger( TestTryCatch.MyBean.class ).info( "processing
Integer: " + obj );
else
throw new IllegalArgumentException( "Need an Integer, please!" );
}
}
public class MyOtherBean {
public void process( Object obj ) {
Logger.getLogger( TestTryCatch.MyBean.class ).info( "processing: " +
obj );
}
}
@Test
public void test() throws Exception {
Registry registry = new Registry() {
public Object lookup( String name ) {
return null;
}
public <T> T lookup( String name, Class<T> type ) {
return null;
}
};
CamelContext cc = new DefaultCamelContext( registry );
@SuppressWarnings("unchecked")
final Endpoint<Exchange> in = cc.getEndpoint( "direct:in" );
@SuppressWarnings("unchecked")
final Endpoint<Exchange> out = cc.getEndpoint( "log:out" );
@SuppressWarnings("unchecked")
final Endpoint<Exchange> error = cc.getEndpoint( "log:error" );
final MyBean myBean = new MyBean();
final MyOtherBean otherBean = new MyOtherBean();
cc.addRoutes( new RouteBuilder() {
@Override
public void configure() throws Exception {
RouteType s = from(in);
TryType t = s.tryBlock();
t.bean( myBean ).to( out );
t.handle( java.lang.Exception.class ).bean( otherBean ).to( error );
}
} );
cc.start();
CamelTemplate<Exchange> t = new CamelTemplate<Exchange>(cc);
t.sendBody( in, Integer.valueOf( 10 ) );
t.sendBody( in, "This will fail..." ); // the catch handler will not
process this correctly!
Thread.sleep( 1000 );
}
}
