Hi,

I have an issue with logstash jdbc plugin configuration for MSSQL.

My config file:

```auto
input {
    jdbc {
      jdbc_driver_library => "/opt/elastic/drivers/mssql-jdbc-10.2.0.jre11.jar"
      jdbc_driver_class => "com.microsoft.sqlserver.jdbc.SQLServerDriver"
      jdbc_connection_string => "jdbc:sqlserver://0.0.0.0:1433;databaseName=solarwindsbd_rst;"
      jdbc_user => "user_elk"
      jdbc_password => "pass"
      statement => "SELECT SYSDATETIME() \"SYSDATETIME\",CURRENT_TIMESTAMP\"CURRENT\",GETDATE()\"GET\";"
      jdbc_validate_connection => true
    }
}
filter {

}
output {
  #elasticsearch {
  # hosts => ["clusterECS"]
  # user => "elastic"
  # password => "pass"
  # index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{[alp]}-%{+YYYY.MM}"
  #}
  stdout { codec => rubydebug }
}

```

I had an error before this one and I dont know if it is related  
Error 1:

```auto
jdbc - Unable to connect to database. 
Tried 1 times {:message=>"Java::ComMicrosoftSqlserverJdbc::SQLServerException:

```

For resolve this error I change the java.security file  
From this:

```auto
jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

```

To this:

```auto
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

```

**After this change the error is this:**

```auto
[ERROR] 2022-02-28 12:40:13.792 [[main]<jdbc] jdbc - Unable to connect to database. 
Tried 1 times {:message=>"Java::ComMicrosoftSqlserverJdbc::SQLServerException:

```

Do you know which could be the cause of this error??
