Issue

• We are currently using Camel's cache component to cache static data. There is no problem retrieving and setting the cache data. However the data that in the cache is getting lost after 15 or 16 minutes even after specifying eternal=true in the cache endpoint.
• Code References:

public class CacheRouteBuilder extends RouteBuilder {

        @Override
    public void configure() throws Exception {
        // TODO Auto-generated method stub

        onException(Exception.class)
            .handled(true)
            .to("direct-vm:exceptionResponse");
        //ESB Service Cache Data        
        from("cache://ESBServiceCache?eternal=true")
            .to("mock:dummy");
        //Expects headers KEY and VALUE
        from("direct-vm:setCacheData")
            .log("Client save Request Recevied...")
            .beanRef("cacheSvcsImplBean", "setCacheData")
            .to("cache://ESBServiceCache");
        //Expects header KEY
        from("direct-vm:getCacheData")
            .log("Client Get Value Request Recevied...")
            .beanRef("cacheSvcsImplBean", "getCacheData")
            .to("cache://ESBServiceCache");     

    }
}

public void setCacheData(Exchange exchange) {
        LOG.info(" Inside setCacheData keyString >>>::<<<<<<< " + exchange.getIn().getHeader());
        String keyData = exchange.getIn().getHeader("KEY").toString();
        String valeData = exchange.getIn().getHeader("VALUE").toString();
        exchange.getIn().setHeader(CacheConstants.CACHE_OPERATION, CacheConstants.CACHE_OPERATION_ADD);
        exchange.getIn().setHeader(CacheConstants.CACHE_KEY, keyData);
        exchange.getIn().setBody(valeData);
    }

    public void getCacheData(Exchange exchange) {
        LOG.info(" Inside getCacheData keyString >>>::<<<<<<< " + exchange.getIn().getHeader());
        String keyValue = exchange.getIn().getHeader("KEY").toString(); 
        exchange.getIn().setBody(null);
        exchange.getIn().setHeader(CacheConstants.CACHE_OPERATION, CacheConstants.CACHE_OPERATION_GET);
        exchange.getIn().setHeader(CacheConstants.CACHE_KEY, keyValue);
    }
