Problems with autoPasswordUtilities1.0 using Java EE 6

[x8-ball]

Describe the bug
Hi, I'm having some problems getting my project to run. The Problem is PasswordUtilities1.0 using Java EE 6.

CWWKF0047E: The io.openliberty.mpCompatible-4.0 and com.ibm.websphere.appserver.javax.connector-1.6 features cannot be loaded at the same time. The io.openliberty.mpCompatible-4.0 feature of Java EE 8 is incompatible with the com.ibm.websphere.appserver.javax.connector-1.6 feature of Java EE 6. The configuration includes an incompatible combination of Java EE features that is not supported. The mpConfig-2.0 and io.openliberty.autoPasswordUtilities1.0.javaee configured features include an incompatible combination of features. Your configuration is not supported. Update the configuration to use compatible versions of the configured features that support the Java EE 8 or Java EE 6 programming models.

CWWKF0033E: The singleton features com.ibm.websphere.appserver.javax.connector.internal-1.7 and com.ibm.websphere.appserver.javax.connector.internal-1.6 cannot be loaded at the same time. The configured features cdi-2.0 and io.openliberty.autoPasswordUtilities1.0.javaee include one or more features that cause the conflict. Your configuration is not supported; update server.xml to remove incompatible features.

CWWKF0046W: The configuration includes an incompatible combination of features. As a result, the feature manager did not install any features.

Steps to Reproduce
Using below features with below version should reproduce problem.

Expected behavior
No Problems building server.xml

There was a small change in 21.0.0.7 for featureUtiliity that affected how plugins resolve features. It will be fixed by OpenLiberty/ci.common#277 and will be released by the end of the month.
