Well your issue is due to you are not changing the size of arrayToHandle, when repeated elements are removed by Set cardSet take into account that the size of the new array is also changing, in this case from 7 to 6, [DJ] is removed, and when you're filling arrayToHandle with the new elements at the end you are not deleting the last position which is the problem you have to, try this:

You have a couple of typos in your YAML so the files aren’t equivalent. You have username and password in the properties file but data-username and data-password in the YAML.

This misconfiguration means that Hibernate cannot connect to the database to detect the dialect that it should use. As a result it required the dialect to be configured instead.

I believe you can fix the problem by correcting the YAML:

You're missing on some configuration, for example generate-dll. Try with the following:

If you call warehouse.setAddress(newAddress); first you modify the managed entity (managed entity because you have fetched the warehouse from the database => now managed by hibernate). After that you are performing a query operation => Hibernate flushes your previous changes to the database to prevent dirty reads before performing the database query operation. In this case the properties of newAddress are not set which leads to the constraint violation exception. Same goes for the

Hibernate seems to "magically" populate the id field in WarehouseAddress after calling newAddress.setProvince(provinceService.findByCode("AR-C"));,

The WarehouseAddress gets persisted before performing the query operation and has therefore an id.

You can use the following solution. We use .x to refer to every individual element of your list. Here .x can be each of your data frames of which we would like to select only 2 columns c("individual","theta"). However, since only one of your data frames contains such column names I used keep function to actually keep only elements whose data frames contain the desired column name. Just bear in mind for this form of coding which is called purrr-style formula we need ~ before .x. So you use map function which is an equivalent to lapply from base R and use this syntax to apply whatever function on every individual elements (data frames here).

You've got at least 3 things wrong here.

1. ARG values are scoped, and go out of scope when you start the next stage.
2. ARG values are for build time (building the image), for runtime (when you start the container from the image) you need to set an ENV.
3. Docker doesn't expand variables in RUN, CMD, or ENTRYPOINT. Instead you get the value injected as an environment variable. To expand the $var syntax to the value of the variable, you need a shell like /bin/sh. The json/exec syntax explicitly bypasses running your command with a shell.

The result looks like:

Most likely openjdk:8 base Docker image that you used doesn't support TLS version required by AWS Aurora. You have to review which TLS version is allowed by your AWS Aurora and then make sure that Java installed in your Docker image supports it. You can take a look at this answer or this answer.

Please note that recently, in April 2021, Java™ SE Development Kit 8, Update 291 (JDK 8u291) changed allowed TLS versions:

➜ Disable TLS 1.0 and 1.1

TLS 1.0 and 1.1 are versions of the TLS protocol that are no longer considered secure and have been superseded by more secure and modern versions (TLS 1.2 and 1.3).

These versions have now been disabled by default. If you encounter issues, you can, at your own risk, re-enable the versions by removing "TLSv1" and/or "TLSv1.1" from the jdk.tls.disabledAlgorithms security property in the java.security configuration file.

You can use the @Value annotation to pull the properties and also their defaults.

It was my fault from the start: It was automatically checked from the checkbox in IntelliJ "Spring Security". I unchecked it and it all worked.
