Joel Richard created JCR-3846:
---------------------------------
Summary: XPath query fails with "data is not a RelationQueryNode"
if the node name starts with a number
Key: JCR-3846
URL: https://issues.apache.org/jira/browse/JCR-3846
Project: Jackrabbit Content Repository
Issue Type: Bug
Components: query, xpath
Affects Versions: 2.6.2
Reporter: Joel Richard
The query {code}/jcr:root/home/users/1//element(*,rep:User){code} fails with
the following error:
{code}Caused by: javax.jcr.query.InvalidQueryException: Parse error: data is
not a RelationQueryNode

If you change the node "1" to "1a", the error is even more obscure:
{code}Encountered "//" at line 1, column 34. Was expecting one of: ... ... ...
... " ... ... ... ... ... ... ... ... ... ... ... ... "$" ... ... ... ... ...
... ... ... ... ... ... ... ... ... ... "*" ... ... ... "(" ... "@" ... ... ...
... ... ... ... ... ... ... ... ... ... ... ... ... ... ... "." ... ".." ...
... "<" ... "<" ... "{code}
Everything works fine if the node starts with a letter, for example "a1".
