---------------------------------
Summary: DescendantContext.nextNode() produce infinite loop
Key: JXPATH-157
URL: https://issues.apache.org/jira/browse/JXPATH-157
Project: Commons JXPath
Issue Type: Bug
Affects Versions: 1.3
Environment: Windows XP, JDK 6
Reporter: Gerd Gühne
Priority: Blocker
Fix For: 1.4
While using "descendant::children" the class DescendantContext produces an
infinite loop in method nextNode() on line 114:
if (it.setPosition(it.getPosition() + 1)) {
The method "setPosition" returns true every time and the stack increases with a
new child iterator on every loop.
The reason is that we have an object with property "baseUnit", that returns a
new object on every call. The class "BeanPropertyPointer" gets all properties
from this object and returns a "PropertyDescriptor" for "baseUnit" property.
But for this property a new object is returned and also a new
"PropertyDescriptor" and so on.
e.g.
/children[1]/children[1]/children[1]/children[1]/children[1]/children[1]/masterData/netInclusion/alocatLimitEntryBioMuePMax/defaultQuantityAndUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit/baseUnit
[..]
We need to configure the maximum iterations of the object path.
