I think you are getting currentNode and resource as null in the included script may be because you are setting "path" as virtual as it is pointing to a non existent node in CRX. If that node does not exist then these tags won't inject the resource/node in the request context for processing. Whatever node you want to access in the included JSP, you should set the path to that particular node. Please see the documentation here - https://docs.adobe.com/docs/en/cq/5-6/howto/taglib.html#%3Ccq:include...

You can specify the proxy server using the following code snippet. Just add these lines before you make the connection. System.setProperty("http.proxyHost", "");System.setProperty("http.proxyPort", "");Or you can pass them in arguments as system properties to the java program-java -Dhttp.proxyHost= -Dhttp.proxyPort=

I guess the intent of having this was to limit the number of nested/recursive calls. In this case, you should be monitoring the JVM memory usage (especially the stack size) and tune it as per the needs. I don't think this should cause AEM to fail but you would be required to tune the JVM. https://issues.apache.org/jira/browse/SLING-601https://mail-archives.apache.org/mod_mbox/sling-users/201202.mbox/%3C4A309956-28F4-4080-88A8-4B447C188BF7@adobe.com%3Ex/sling-users/201202.mbox/%3C4A309956-28F4-40...
