/**
 * HSQLDB TestBugBase Junit test case. <p>
 *
 * By setting the booleans isNetwork, isHTTP, isUseTestServlet below, you can execute all tests that derive from this TestBase class
 * using either the embedded HSQL server mode in both HSQL or HTTP protocol, or target the HSQL-Servlet mode running in for example
 * Tomcat.
 *
 * When running against the Servlet: This assumes you have a WebApplication called HSQLwebApp running in for example Tomcat, with hsqldb.jar
 * (or better hsqldbtest.jar renamed to hsqldb.jar) in the WEB-INF/lib directory and web.xml containing something like this:<p>
 *      <code>
 * {@literal
 *    <servlet>
 *      <servlet-name>test</servlet-name>
 *      <servlet-class>org.hsqldb.server.Servlet</servlet-class>
 *      <init-param>
 *            <param-name>hsqldb.server.database</param-name>
 *            <param-value>mem:test</param-value>
 *      </init-param>
 *      <load-on-startup>1</load-on-startup>

 *    <servlet-mapping>
