Here is the typical Java code I am using for Flyway:
Flyway flyway = new Flyway();
flyway.setBaselineOnMigrate(true);
flyway.setDataSource(this.dataSource);
flyway.migrate();

There is an exception when the Flyway execute the baseline migration:
Unable to insert row for version '1' in metadata table schema_version

SQL State : JZ006
Error Code : 0
Message : JZ006: Caught IOException: java.io.IOException: JZ0SL: Unsupported SQL type 0.

As I debugged the code, the error is caused by following code in JdbcTemplate of Flyway library:
private PreparedStatement prepareStatement(String sql, Object[] params) throws SQLException {
PreparedStatement statement = connection.prepareStatement(sql);
for (int i = 0; i < params.length; i++) {
if (params[i] == null) {
statement.setNull(i + 1, nullType); // this line causes the error when the checksum is a null integer. It seems Sybase connector doesn't know the null type.
} else if (params[i] instanceof Integer) {
statement.setInt(i + 1, (Integer) params[i]);
} else if (params[i] instanceof Boolean) {
statement.setBoolean(i + 1, (Boolean) params[i]);
} else {
statement.setString(i + 1, (String) params[i]);
}
}
return statement;
}

As I see it, it should be the problem of the Sybase jConnect, however, the Flyway library should be robust enough to handle such situations because it may happen on any database which doesn't support the java.sql.Types.

What did you expect to see?

No exception is thrown for Sybase.
