resteasy @Consume json fails with java.util.Map

I have the following json structure:

{
    "foo" : {
        "foo1" : {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        },
        "foo2" : {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        }
    },
    "bar" : {
        "bar1": {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        },
        "bar2": {
            "txt" : "val",
            "txt1" : "val1",
            "txt2" : "val2",
        }
    }
}

While i have the following pojo:

class Pojo {
  String txt;
  String txt1;
  String txt2;
}

And my resteasy method looks like:

@POST
@Produces({ MediaType.APPLICATION_JSON })
@Consumes({ MediaType.APPLICATION_JSON })
@Path("/foo")
public void bar(@QueryParam("jsonObj") Map<String,Map<String,Pojo>> jsonObj);

However while starting the server i get the following error:

java.lang.RuntimeException: Unable to find a constructor that takes a String param or a valueOf() or fromString() method for javax.ws.rs.QueryParam("jsonObj") on public abstract void com.foo.FooBar.bar(java.util.Map) for basetype: java.util.Map at org.jboss.resteasy.core.StringParameterInjector.initialize(StringParameterInjector.java:217) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.StringParameterInjector.(StringParameterInjector.java:61) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.QueryParamInjector.(QueryParamInjector.java:28) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.InjectorFactoryImpl.createParameterExtractor(InjectorFactoryImpl.java:85) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.MethodInjectorImpl.(MethodInjectorImpl.java:42) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.InjectorFactoryImpl.createMethodInjector(InjectorFactoryImpl.java:76) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodInvoker.(ResourceMethodInvoker.java:100) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodRegistry.processMethod(ResourceMethodRegistry.java:280) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodRegistry.register(ResourceMethodRegistry.java:251) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodRegistry.addResourceFactory(ResourceMethodRegistry.java:221) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodRegistry.addResourceFactory(ResourceMethodRegistry.java:193) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.core.ResourceMethodRegistry.addResourceFactory(ResourceMethodRegistry.java:179) ~[resteasy-jaxrs-3.0.9.Final.jar:na] at org.jboss.resteasy.plugins.spring.SpringBeanProcessor.onApplicationEvent(SpringBeanProcessor.java:486) ~[resteasy-spring-3.0.9.Final.jar:na] at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:96) ~[spring-context-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.context.support.AbstractApplicationContext.publishEvent(AbstractApplicationContext.java:334) ~[spring-context-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.context.support.AbstractApplicationContext.finishRefresh(AbstractApplicationContext.java:948) ~[spring-context-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:482) ~[spring-context-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:410) ~[spring-web-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:306) ~[spring-web-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:112) [spring-web-3.2.8.RELEASE.jar:3.2.8.RELEASE] at org.jboss.resteasy.plugins.spring.SpringContextLoaderListener.contextInitialized(SpringContextLoaderListener.java:48) [resteasy-spring-3.0.9.Final.jar:na] at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4939) [catalina.jar:7.0.47] at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5434) [catalina.jar:7.0.47] at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) [catalina.jar:7.0.47] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) [catalina.jar:7.0.47] at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) [catalina.jar:7.0.47] at java.util.concurrent.FutureTask.run(FutureTask.java:262) [na:1.7.0-45] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) [na:1.7.0-45] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) [na:1.7.0-45] at java.lang.Thread.run(Thread.java:744) [na:1.7.0-45]

I went through the documentation and for Complex Objects it says to use StringConvertor, but shouldn't it be supported for a simple types like List, Map etc...

Instead of taking the JSON in Map> jsonObj format , you can use InputStream and then you can process the input stream to get the objects out of it.
