Stop using illegal reflective access

[mustafashabib]

Hi All

We're on gradle 5.1 and are seeing this message during builds using spring-data-jpa-entity-graph v2.07.

WARNING: An illegal reflective access operation has occurred

Just wanted to report it in case it's useful.

Hi @mustafashabib ,

Thanks for the bug report.
I hope to fix this issue once https://jira.spring.io/browse/DATAJPA-1497 is fixed.

[mvmn]

BTW - some of the tests seem to be failing for your PR there, and also it seems to have merge conflicts now.

[reda-alaoui]

Yes I saw that, I will fix it asap ;)

[reda-alaoui]

The reference to the Spring Data JPA PR => spring-projects/spring-data-jpa#305

[reda-alaoui]

Merge conflict fixed.
Waiting to see if the build turns to green.

[reda-alaoui]

Looks like they removed the build step from their PRs.
Just have to wait for review now.

[reda-alaoui]

The PR was rejected => https://jira.spring.io/browse/DATAJPA-1497

Hello @reda-alaoui

Any update about the rejected PR ? Will you try to convince them to accept it, or is there any workaround (except disabling illegal access) ?

I have been using your library for a few months and I really like it, it fits my needs perfectly :-) but if the support will stop with Java 12, I should unfortunately reconsider it for some of our projects :(

Thanks in advance !

Hello @jplumez ,

I am planning to retry convincing them.
But I think the more we are, greater are the chances to convince them.
So I hope you will let a comment on https://jira.spring.io/browse/DATAJPA-1497 or on spring-projects/spring-data-jpa#305.

[reda-alaoui]

FYI, meanwhile, I think you can still permit illegal access with --illegal-access=permit, even with JDK 12.

I have commented on the spring issue to add more support from users :)

[reda-alaoui]

spring-projects/spring-data-jpa#305 was merged ! 🍾

The first Spring Data JPA version to contain spring-projects/spring-data-jpa#305 fix will be 2.3.0. Therefore the current issue fix will be available starting with spring-data-jpa-entity-graph 2.3.0.

[reda-alaoui]

Spring Data JPA 2.3.0.RELEASE is now available.
You can now fix the issue by:

• upgrading to Spring Data JPA 2.3.0.RELEASE

and

• upgrading to Spring Data JPA EntityGraph 2.3.0
