Description

I saw in the camel 2.19.0 release notes that xml routes could be reloaded automatically which woke my interest (since we only use xml routes and no java at all). I tried it by specifying the fileWatcherDirectory in my pom.xml (in the camel-maven-plugin configuration) and it worked fine for me. I ran it from within eclipse.
The point is that our camelcontext only holds routeContextRef entries and no real routes. I tried again by specifying the location src/main/resources (where the routecontext files are) but this does not seem to work, no updates are seen.

Claus point me to look in the source code and I saw that ReloadStrategySupport.java holds line 76:

dom = XmlLineNumberParser.parseXml(new ByteArrayInputStream(xml.getBytes()), null, "camelContext,routes", "http://camel.apache.org/schema/spring");

which means that routes from a routeContext are NOT reloaded.

This could be solved by changing the line to:

dom = XmlLineNumberParser.parseXml(new ByteArrayInputStream(xml.getBytes()), null, "camelContext,routes,routeContext", "http://camel.apache.org/schema/spring");
