InaccessibleObjectException while executing tests with JDK17

[nskshared]

hi
We are getting below error while running our tests against POJO classes. Looks like they increased security levels in jdk17 hence its difficult to change access modifiers etc.

Please can you advise if there is any alternative for below issue.

Unable to make field private static final long java.time.LocalDate.serialVersionUID accessible: module java.base does not "opens java.time" to unnamed module @6be46e8f
java.lang.reflect.InaccessibleObjectException: Unable to make field private static final long java.time.LocalDate.serialVersionUID accessible: module java.base does not "opens java.time" to unnamed module @6be46e8f

Same Problem with Map: Unable to make field private static final java.util.Map java.util.Locale.CONSTANT_LOCALES accessible: module java.base does not "opens java.util" to unnamed module @757942a1

I got the same issue for java.time.LocalDate.serialVersionUID. After looking at the stacktrace found out that openpojo is trying to generate a random value for LocalDateTime which was used in one of my class.
There are 2 possible solutions to get over this error.

• Add jvm arguments to your gradle test task to bypass the restriction.
  --add-opens java.base/java.time=ALL-UNNAMED (change the package depending the class that you are getting the error for)
• Add a custom RandomGenerator for LocalDateTime as mentioned here https://github.com/OpenPojo/openpojo/wiki/Tutorial-7.-Adding-A-New-Random-Generator

I tried the workaround suggested above but it didn't work for me.

This is a major issue, but it doesn't seem like this project has gotten much attention lately. Wondering if it will ever be addressed.

@vmgbrown Did neither of the two options work for you? Which one did you try? We were migrating 20 of our services and these work arounds worked for us always. Just curious.

@rahul-konduru Sorry I wasn't clear. I tried the --add-opens workaround. We use OpenPOJO in a lot of tests, so any sort of custom workaround is likely to be a non-starter.

My bigger issue is the lack of updates. If this project is not being maintained, we will most likely need to look into other options.

Its the same case with us. Lots of dependency on this library and couldn’t replace it for now. There is a catch if you are using —add-opens option. The package name is the key. For example if there are multiple classes with the error, you need to add the arguments those many times. For example, if you get the error for the following classes (the nesting example is intensional) com.a.Class1 com.a.b.Class2 You need to add these two arguments —add-options java.base/com.a=ALL-UNNAMED —add-options java.base/com.a.b=ALL-UNNAMED Hope this helps.

@rahul-konduru The custom generator case is working for now. Thank you for the suggestion!
