Oracle 12 error using json blob Column : No more data from read socket

I am saving information that comes from a kafka topic in an oracle 12c table that contains a blob type column with the restriction that it is a json, to do this I use apache camel and jpa. After 9 days of running in production I got the following error every time I want to update a record:

When I execute a delete on the table using SQL developer I also get a similar error
Error en la línea de comandos : 1 Columna : 1
Informe de error -
Error SQL: No hay más datos para leer del socket
In jpa I am using this https://github.com/vladmihalcea/hibernate-types to save information in json format. The table has a partition of type range by days, I have no errors when an insert is executed.
I need your help to know why this error occurs and how to solve it, please. I request the logs from the database to the dba but it tells me that there are no errors.

Process finished with exit code 1
I delete some of my error messages because that is too long. Besides, in my java code, I used
try {
Class.forName("org.mysql.Driver");
String jdbcConnString = "jdbc:mysql://my_endpoint_in_aws_rds:3306/my_db_name";
String jdbcUser = "my_username";
String jdbcPassword="my_password";
myConnection = DriverManager.getConnection(jdbcConnString, jdbcUser, jdbcPassword);
}
I already set my AWS security group inbounds rules to accept all TCP and ICMP-IPv4, which includes my Public IP address, but it still has a communication link failure.
I can use workbench on my local to connect to my AWS RDS with the endpoint, username and password.
I have no idea what's the reason, I've tried several methods but still doesn't work.
Do I miss something?

You are using mysql. Add the dependency to your pom.xml or graddle.settings
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
Add the values to your application.properties file.
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.ddl-auto=update
spring.datasource.hikari.jdbc-url=ADD-TO-HERE-DATABASE-URL
spring.datasource.hikari.username=ADD-TO-HERE-DATABASE-USERNAME
spring.datasource.hikari.password=ADD-TO-HERE-DATABASE-PASSWORD
spring.datasource.hikari.driver-class-name=com.mysql.cj.jdbc.Driver
Then create a class for hikari config.
import com.zaxxer.hikari.HikariDataSource;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.sql.DataSource;
#Configuration
#ConfigurationProperties(prefix="spring.datasource.hikari")
public class HikariConfig extends com.zaxxer.hikari.HikariConfig {
#Bean
public DataSource dataSource() {
return new HikariDataSource(this);
}
}
And that's it. I've done a simple project before.You can see an example. click
Also look at these docs.

Hibernate and eclipse editor

I updated eclipse to the latest version, installed latest jboss tools hibernate, and the hibernate HQL editor stopped working. My webapp code is running fine though. Is there a way to fix this? currently installed jdk jdk-11.0.10

Can you give an exact description of the following info:
the version of Eclipse and JBoss Tools that you are using
the version of Hibernate (ORM and Tools) that you are using
the database (and version) that you are using
In addition, it would absolutely be helpful if you create a minimal project that exposes the problem and describe the different steps to reproduce the issue:
creation of the Hibernate Console
which HQL are you trying to execute from this console
Cheers,
Koen

I can connect to Oracle 19C with the above URL in SQL Developer.
Here is a screenshot.
listener.ora
tnsnames.ora
I tried to use "DESKTOP-KUC7NN8" in connection string as a host name. But same error!

I made a typo in defining the data source URL. Port was wrong!
Wrong: jdbc:oracle:thin:#//localhost:1251/ORCL
Correct: jdbc:oracle:thin:#//localhost:1521/ORCL

How to parse exception message and log ut?
