InvalidDefinitionException after upgrading from 2.9.1 to 2.9.2

This is (re)submission of https://github.com/FasterXML/jackson-databind/issues/1817 after @cowtowncoder asked me to submit it here.

I’m using Kotlin and I’ve just upgraded from Jackson version 2.9.1 to 2.9.2. Previously the following was working:

val parsed = jsonMapper.readValue(result.output, DockerHealthCheckStatus::class.java)

But now it fails with the following exception:

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Invalid definition for property `Log` (of type `batect.docker.DockerClient$DockerHealthCheckStatus`): Could not find creator property with name 'Log' (known Creator properties: [log])

Parser is set up with:

    private val jsonMapper by lazy {
        val mapper = jacksonObjectMapper()
        mapper.propertyNamingStrategy = PropertyNamingStrategy.UPPER_CAMEL_CASE
        mapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)

        mapper
    }

DockerHealthCheckStatus is defined as:

    private data class DockerHealthCheckStatus(val log: List<DockerHealthCheckResult>)

Am I doing something wrong or is this a bug introduced in 2.9.2?

@apatrida I can confirm that this bug is also affecting single-constructor data class with a parameter other than a string. In my case, the class holds a single UUID? property:

Invalid definition for property `account_id` (of type `com.movile.kiwi.ws.web.controller.event.v2.to.AccountInfoTO`): Could not find creator property with name 'account_id' (known Creator properties: [accountId])
 at [Source: (com.movile.kiwi.ws.web.filter.model.ResettableStreamHttpServletRequest$ResettableServletInputStream); line: 1, column: 1]

The class definition is:

data class AccountInfoTO(val accountId: UUID?)

If I add an explicit @JsonProperty annotation or add a dummy empty property the binding works as expected.

I think all issues mentioned here are resolved in current releases (or master branch of this plugin)
