为什么Spring批处理不支持Informix？

Question

    ERROR o.s.boot.SpringApplication -Application run failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configurer': Invocation of init method failed; nested exception is org.springframework.batch.core.configuration.BatchConfigurationException: java.lang.IllegalArgumentException: DatabaseType not found for product name: [Informix Dynamic Server]
Caused by: org.springframework.batch.core.configuration.BatchConfigurationException: java.lang.IllegalArgumentException: DatabaseType not found for product name: [Informix Dynamic Server]
Caused by: java.lang.IllegalArgumentException: DatabaseType not found for product name: [Informix Dynamic Server]

这是Spring DatabaseType类：

public enum DatabaseType {

    DERBY("Apache Derby"),
    DB2("DB2"),
    DB2VSE("DB2VSE"),
    DB2ZOS("DB2ZOS"),
    DB2AS400("DB2AS400"),
    HSQL("HSQL Database Engine"),
    SQLSERVER("Microsoft SQL Server"),
    MYSQL("MySQL"),
    ORACLE("Oracle"),
    POSTGRES("PostgreSQL"),
    SYBASE("Sybase"),
    H2("H2"),
    SQLITE("SQLite");

任何可以解决的工作示例都会得到应用？
