title: FBDriver reporting warnings I can't figure out how to fix
body: <p>I'm developing a RESTful application and whenever I make a request, it works fine, but also outputs these warnings:</p>
  <pre class="lang-none prettyprint-override"><code>o.h.engine.jdbc.spi.SqlExceptionHelper   : SQL Warning Code: 0, SQLState: null
  o.h.engine.jdbc.spi.SqlExceptionHelper   : Connection.isValid does not support non-zero timeouts, timeout value 5 has been ignored
  </code></pre>
  <p>Using Spring Boot framework with Hibernate, HikariCP, QueryDSL and a Firebird database using the Jaybird 4.0.5.java11 version.</p>
  <p>Here is my <code>application.yml</code> file where I setup the connection with my database:</p>
  <pre><code>spring:
    datasource:
      driver-class-name: org.firebirdsql.jdbc.FBDriver
      url: jdbc:firebirdsql://localhost:3050/C:\\path\\to\\my\\database.fdb?encoding=win1252
      username: myuser
      password: mypassword
      hikari:
        connection-timeout: 1000
        login-timeout: 1000
        minimum-idle: 10
  
    jpa:
      database-platform: org.hibernate.dialect.FirebirdDialect
      hibernate:
        ddl-auto: validate
  </code></pre>
  <p>I've tried all options I could to setup a timeout but none of them made the timeout warning go away.</p>
  <p>Also, I can't figure out that SQL Warning Code: 0, from what I've gathered so far, it means it worked, but why is it outputting a warning?</p>
  <p>I should mention that I've altered some sensitive information and they were replaced with <code>path\\to\\my\\database.fdb</code>, <code>myuser</code> and <code>mypassword</code>, but these settings work just fine.</p>
