Previously, a dependency on jackson-module-kotlin with Kotlin excluded
was added to spring-boot-starter-json. This gave Kotlin users a smooth
experience with Jackson and JSON at minimal, we thought, cost to other
users. We have since learned that this arrangement causes a
ClassNotFoundException at runtime when Jackson is configured to find
modules via the service loader. This makes the cost of including
jackson-module-kotlin to high for non-Kotlin users so this commit
removes it.

Elasticsearch server requires log4j-core but we don't want the entire
module to have a test dependency on log4j-core as it already uses
Logback. This commit uses the modified class path runner to make
log4j-core available specifically to the Elasticsearch-related tests.

  Remove a redundant dash in TestPropertyValues.Type

Closes gh-11156

Prior to this change, the dash was duplicated. For example
"test--systemEnvironment". This commit removes the redundant dash
and corrects the assertion in the test that should have caught the
problem.
