Description

We're using a custom javax.ws.rs.core.Application implementation, "com.foo.BasicApplication", injected via Spring XML into a JAXRSServerFactoryBean. I've been seeing some inconsistent behavior at intialization. About half the time I get this:

WARN  [] [org.springframework.beans.GenericTypeAwarePropertyDescriptor] - Invalid JavaBean property 'application' being accessed! Ambiguous write methods found next to actually used [public void org.apache.cxf.jaxrs.JAXRSServerFactoryBean.setApplication(javax.ws.rs.core.Application)]: [public void org.apache.cxf.jaxrs.JAXRSServerFactoryBean.setApplication(org.apache.cxf.jaxrs.model.ApplicationInfo)]

which complains about it, but in this case it still works.

The other half of the time I get this, and the application fails to start up:

org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.foo.BasicApplication' to required type 'org.apache.cxf.jaxrs.model.ApplicationInfo' for property 'application'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.foo.BasicApplication] to required type [org.apache.cxf.jaxrs.model.ApplicationInfo] for property 'application': no matching editors or conversion strategy found

Is this not a supported configuration? I found a workaround of creating a wrapper class that proxies the setter call without the ambiguity, but it's not ideal.
