[BUG] Enumeration in path generates wrong java

Description

When an enumeration is used as a parameter in a path the generated springboot server has both wrong annotations (quotes where there shouldn't be quotes) and wrong actual accepted values (capital letters instead of lower case) for the enumerated values.

Steps to reproduce

• Generate java server as above
• Expected result:
  ** Java server accepts string in path with allowed values of nightly, continuous, pull, deploy, test, or push
• Actual result:
  ** Generated code has annotation @ApiParam(value = "A job that is running or can be run",required=true, allowableValues = ""nightly", "continuous", "pull", "deploy", "test", "push"") <- Note quotes that should not be there
  ** Actual accepted values are NIGHTLY, CONTINUOUS, PULL, DEPLOY, TEST, and PUSH <- Note captialisation

Reproduce the issue with the Maven plugin using the supplied api.yaml, generatorName spring, and spring-boot library configuration. Compare the generated path parameter annotations and accepted enum values with the expected lowercase nightly, continuous, pull, deploy, test, and push values; done means the extra annotation quotes and uppercase values are gone.
