• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 2.3.0

Description

A variant of IVY-1333 is possible with some interesting properties:

• Mediations having an effect on resolution (presence being necessary to trigger the issue in question) even when no children of the descriptors to which they apply match their specifiers.
• IllegalStateException only triggering when multiple confs are resolved in a single pass.

See attached reproducer. Using same, the exception excerpted below is thrown:
