APAR PH37460 useJandex is ignored when autoExpand is set

[tbitonti]

Title: 'useJandex' is ignored when 'autoExpand' is enabled.
Abstract: Setting 'autoExpand' to true causes the 'useJandex' setting to be ignored.
Description:
'autoExpand' and 'useJandex' may be configured per application and for all applications.
For example:

  <applicationManager autoExpand="true" useJandex="true"/>
  <application location="TS.war"/>

Or:

  <application location="TS.war" autoExpand="true" useJandex="true"/>

When 'useJandex' is configured for an application, an informational message is expected for that application. For example:

[5/21/21 11:33:06:613 EDT] 0000003e com.ibm.ws.annocache I CWWKC0093I: Jandex coverage of module TS in application TS: Jandex indexes were read for 2 out of 2 module locations; Jandex indexes provided 3 out of 3 module classes.

When 'autoExpand' is configured to true, the 'useJandex' setting is ignored.

---

Describe the bug
See the APAR text, above.

Steps to Reproduce
Configure an application to have 'useJandex' and 'autoExpand' both enabled.

Expected behavior
Enabling 'useJandex' should cause Jandex indexes within the application to be used. This will be shown by an informational message 'CWWKC0093I:' being produced.

Diagnostic information:

• Liberty version 21.0.0.3 and higher.
• Java version: Does not matter.
• Server configuration: See the APAR text, above.
