HSQL server mode while connection from DatabaseSwingManager throws exception java.sql.SQLTransientConnectionException - database-connection

Question

I have written a java code of connecting to server mode
p.setProperty("server.database.3",
"file:G:/SERVERMODE/soamware;user=soamware;password=123#123");
p.setProperty("server.dbname.3", "soamware");
server.setProperties(p);
server.setLogWriter(null); // can use custom writer
server.setErrWriter(null); // can use custom writer
server.start();
try {
//Registering the HSQLDB JDBC driver
Class.forName("org.hsqldb.jdbc.JDBCDriver");
con = DriverManager.getConnection("jdbc:hsqldb:hsql://ip/soamware;
file:G:/SERVERMODE/soamware;user=soamware;password=123#123");
this code is working fine in netbeans with jdk8 and hsqldb2.5.1, however the console shows the build is not terminated and its still running. While when i connect to SwingDatabaseManager
with same url, username and password as mentioned in java code. It throws above mentioned exception. Kindly clarify also, why my program doesnt exit. I am not adding "server.shutdownCatalogs(1);" statement at end because then I cannot perform multiple operations in one session.

Because you are starting the server with only one database, you should set database.0 properties. You shouldn't use the # character at all on a connection string because it has a special meaning. You shouldn't use the file path when connecting to a server database. Use the dbname.0 value only. Edited code below:
p.setProperty("server.database.0", "file:G:/SERVERMODE/soamware;user=soamware;password=123x123");
p.setProperty("server.dbname.0", "soamware");
server.setProperties(p);
server.setLogWriter(null); // can use custom writer
server.setErrWriter(null); // can use custom writer
server.start();
try {
Class.forName("org.hsqldb.jdbc.JDBCDriver");
con = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/soamware", "soamware", "123x123");
