             Summary: PropertyUtils cycle detection results in false positives
                 Key: MSHARED-1290
                 URL: https://issues.apache.org/jira/browse/MSHARED-1290
             Project: Maven Shared Components
          Issue Type: Bug
          Components: maven-filtering
    Affects Versions: maven-filtering-3.3.1
            Reporter: Wouter Born


I upgraded the maven-assembly-plugin in one of my projects from 2.6 to 3.6.0 
and found that {{PropertyUtils}} was logging many false positives about cycles 
between properties.

The cycle detection (introduced for MSHARED-417) reports false positives when a 
variable occurs multiple times in a property, example:
{code:java}
depends=p1 >= ${version}, p2 >= ${version}, p3 >= ${version}
version=1.2.3 {code}
While writing a unit test to fix this, I also found that there are also cycle 
false positives whenever one of the property values is the same as a property 
name, example:
{code:java}
test1=${test2}
test2=test1 {code}
