> Same piece of camel.xml and POJO working in camel 2.9.2.
> Issue encountered in camel 2.9.3 and all above versions.
> When trying to start apache camel embedded inside activemq (or camel starting
> as standalone on Jetty container), I encountered the following exception :
> Caused by: org.apache.camel.TypeConversionException: Error during type
> conversion from type: com.messagetransformers.StringAppenderBean to the
> required type: org.apache.camel.Processor with value
> com.messagetransformers.StringAppenderBean@77b407 due argument type mismatch
> at
> org.apache.camel.impl.converter.BaseTypeConverterRegistry.convertTo(BaseTypeConverterRegistry.java:126)
> at
> org.apache.camel.impl.converter.BaseTypeConverterRegistry.convertTo(BaseTypeConverterRegistry.java:98)
> at
> org.apache.camel.util.CamelContextHelper.convertTo(CamelContextHelper.java:72)
> Extract from my camel.xml
> <bean id="beanTransformer"
> class="com.messagetransformers.StringAppenderBean"/>
> <camelContext xmlns="http://camel.apache.org/schema/spring";>
> <route id="beanTransformRoute" autoStartup="true">
> <description>Transformer Route</description>
> <from uri="activemqRoute1:MY.QUEUE.1"/>
> <bean ref="beanTransformer" method="process"/>
> <to uri="activemqRoute1:MY.QUEUE.2"/>
> </route>
> </camelContext>
> Code snippet from that is causing this issue
> org.apache.camel.impl.converter.BaseTypeConverterRegistry.java(doConvertTo
> method)
> Object rc;
> if (tryConvert) {
> rc = tc.tryConvertTo(type, exchange, value);
> } else {
> rc = tc.convertTo(type, exchange, value);
> }
> The else part is not there in Camel 2.9.2 and is introduced from Camel 2.9.3.
> This code seems to force a normal bean to register as a
> FallbackTypeConverter which is causing the issue.
> Removing the else condition from camel 2.10.3 solved the issue.
> My question is, is it expected that normal bean definitions should fail from
> upwards of camel 2.9.3? Documentation seems to say nothing about it. Please
> help
