Apparent connection leak detected with Hikari CP

Apparent connection leak detected with Hikari CP - java

When using native sql operator IN i get exception. Although it throws an exception, it still works as it was intended, but the exception in the logs is a bit annoying. I think it has something to do with the IN operator.
#Query("select c from Contact c where c.id in :ids")
List<Contact> findByContactsIds(#Param("ids") List<Integer> contactsIds);
config:
spring.datasource.hikari.max-lifetime=900000
spring.datasource.hikari.leakDetectionThreshold=2000
spring.datasource.hikari.idle-timeout=900000
exception:

Why do I have to think all the time what to write so that the validator misses me

You're using a recent version of Hikari CP and the connection leak resolves by itself (as visible in your logs). As noted by #M. Deinum the issue can be caused in a low value of hikari.leakDetectionThreshold property (your "in" query can take much more than 2 seconds). Try to increase it to 60000, then do some tuning based on your response time.

# in spring boot
spring.datasource.hikari.leak-detection-threshold=60000

spring boot : java.lang.IllegalArgumentException: object is not an instance of declaring class

I have setup a spring boot project and using castor xml dependency to convert a POJO to xml.
compile 'org.codehaus.castor:castor-xml:1.3.3'
facing an issue while calling marshal method for a POJO. I have looked up other related questions on stackoverflow but none of them having a solution for my scenario.
There is toString method which is inside a spring component.
Here is the snippet :
public String toString(Client client) throws MarshalException, org.exolab.castor.xml.ValidationException {
String xml = null;
// Create the xml
StringWriter sw = new StringWriter();
client.marshal(sw);
xml = sw.toString();
return xml;
}
And here is the marshal method inside client (auto generated class by castor earlier):
public class Client implements java.io.Serializable {
private static final long serialVersionUID = 5203108777533793020L;
private Object _clientId;
private String _someOtherField;
private List<Address> _addresses; // this is also serialized;
public void marshal(final java.io.Writer out) throws org.exolab.castor.xml.MarshalException,org.exolab.castor.xml.ValidationException{
Marshaller.marshal(this, out);
}
Here is the stacktrace for the same:

Strage thing to notice here is the code works as expected when I execute code from Junit test. but when I invoke the webservice from swagger API, I get the error.

Please "try" the following:
no underscore!
private Object clientId;
private String someOtherField;
private List<Address> addresses;
//and "normal" getters/setters ...
public void setClientId(Object cId) { //...
..my "feeling" is backed by:
In introspection mode , Castor XML uses Java reflection to establish the binding between the Java classes (and their properties) and the XML, following a set of (default) naming rules.
... from castor-xml-doc
The only "defaul naming rules" for "properties" I am aware of are the:
Java Bean Naming Conventions(-> 8.3 Design Patterns for Properties)
... which might explain your described problem/stacktrace. ..See also (e.g.): Bean validation not working if name variable is prefixed with underscore
Still doesn't explain the difference between "test" and "swagger" execution, but to pardon: very few information on this and (I am very confident that) the proposed fix won't break "swagger".
We face a problem, when the effort to eliminate (all) underscores is "huge" ... then we should understand the difference!

Many to many relationship causes exception

Each and every time when I try to add a bidirectional relationship to my entities according to the tutorial from Baeldung (https://www.baeldung.com/hibernate-many-to-many) I get an exception from the "inverse", i.e. "not owning" side of the relationship. My scenario is as the following: A "user" can be in zero to n "pools" and a pool can have zero to n "users". These are my entity classes:
Pool:
#Data
#Entity
#Table(name = "pool")
public class Pool {
//Id and rest of the attributes omitted.
#ManyToMany
#JoinTable(name = "user_pool", joinColumns = {#JoinColumn(name = "pool_id")}, inverseJoinColumns = {#JoinColumn(name = "user_id")})
private Set<User> users;
}
And User:
#Data
#Entity
#Table(name = "agamottto_user")
public class User {
//Id and rest of the attributes omitted.
#ManyToMany(mappedBy = "users")
private Set<Pool> pools;
}
This is the database:
CREATE TABLE IF NOT EXISTS `user_pool` (
`user_pool_id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_id` bigint(20) NOT NULL,
`pool_id` bigint(20) NOT NULL,
PRIMARY KEY (`user_pool_id`),
KEY `user_pool_fk1_idx` (`user_id`),
KEY `user_pool_fk2_idx` (`pool_id`),
CONSTRAINT `user_pool_fk1` FOREIGN KEY (`user_id`) REFERENCES `agamottto_user` (`user_id`),
CONSTRAINT `user_pool_fk2` FOREIGN KEY (`pool_id`) REFERENCES `pool` (`pool_id`)
Now when I use the "PoolRepository" (which extends the JPA Repository) to find a pool by id, I receive the pool with all users as set, so no problem there.
However if I try to get a user with the "UserRepository" I don't get his pools as a set. An exception is thrown instead:

So my questions are:
What's the reason for this behavior and how can I resolve it?
Thanks in advance.

You are using Lombok #Data with a bidirectional relationship.
This is very dangerous because the generated toString() and probably other generated methods will produce a StackOverflowError.
You should replace #Data with #Getter and #Setter and implement equals and hashCode if you need it by yourself.

Spring Boot REST · application.properties property causing NullPointerException

Continuing from my last question, that same property that I needed to add to application.properties to make ConstraintValidator works, spring.jpa.properties.javax.persistence.validation.group.pre-remove, is causing a NullPointerException when I try to delete an entity containing a list of the same type as a member. Simpler entities get deleted just fine. I even removed all validations, but it changes nothing.
Here's a project that's a non operational subset of the project I'm working on, here's the maven dependency tree, and here's the stack trace:

Please help me make it work.
Thanks in advance.

I found the solution (sort of). Actually, I didn't just included that property. It's the removal of the org.springframework.validation.Validators that caused the javax.validation validators to stop working. I found out that I needed to have a org.springframework.validation.Validator registered with the before|afterCreate|Save|LinkSave|Delete events and that I had to either call the complex entity's linked entity getter or change it's fetch = FetchType.LAZY to fetch = FetchType.EAGER.
My colleague gave me the suggestion when I mentioned that the NPE happens at a Hibernate code line that reads if ( persister.isExtraLazy() ) { (see top of stack trace).
Doesn't look like the right way of doing things, but it's working for now. If someone has something to add, I'll be grateful.
