[JAVA] library property overrides/removes information

Description

When using the swagger-codegen-maven-plugin to generate a Java client, I set the regarding information of the developer, scm, description, etc. within the configOptions. Furthermore I set the library to use ('resteasy').

After I generated the client and checked the pom.xml the regarding information (developer, organization, description) were not set.

After removing the <library>resteasy</library> property, the defined information where available again.

Swagger-codegen version

<groupId>io.swagger</groupId>
<artifactId>swagger-codegen-maven-plugin</artifactId>
<version>2.3.1</version>

Configuration

<configOptions>
  <library>resteasy</library>
  <groupId>${project.groupId}</groupId>
  <artifactId>${project.artifactId}</artifactId>
  <artifactVersion>${project.version}</artifactVersion>
  <artifactDescription>A autogenerated ${project.artifactId} client. This client is generated by the produced swagger file of the server.</artifactDescription> <-- MISSING

  <developerName>A Name</developerName> <-- MISSING
  <developerEmail>mail@123.de</developerEmail> <-- MISSING
  <developerOrganization>${project.organization.name}</developerOrganization> <-- MISSING
  <developerOrganizationUrl>${project.organization.url}</developerOrganizationUrl> <-- MISSING

  <scmConnection>${project.scm.connection}</scmConnection>
  <scmDeveloperConnection>${project.scm.developerConnection}</scmDeveloperConnection>
  <scmUrl>${project.scm.url}</scmUrl>

  <java8>true</java8>

<configOptions>

Reproduce the issue with the supplied swagger-codegen-maven-plugin configuration, comparing generated pom.xml metadata with and without the resteasy library setting. Trace the Java client generation path and verify that developer, organization, description, and SCM values remain present when resteasy is selected.
