            Edit

            I did not know MessageDigest is a single use class. You showed an injection of that class, which by definition cannot provide multiple instances. So the question is flawed.

            You must fix the problem by binding a factory function that creates an MD rather than the MD itself. E.g. a Supplier:

            It is necessary to use the FileReaderFactory and FileReader interfaces to get the «Include directories» support.

            As can be seen in the comments of the post, my problem is fixed, so I thought I'd collect a closing answer here to not leave the post pending.

            The actual solution: As explained here nicely by @UninformedUser, the issue was that I had conflicting maven package versions in my dependencies. Bringing everything in sync with each other solved the issue.

            Incidental solution: As I wrote in the comments above, specifically defining 3.3.0 for the maven-assembly-plugin happened to solve the issue. But this was only chance, as explained here by @Ignazio, just because the order of "assembling" things changed, overwriting the conflicting package.

            Huge thanks to both for the help.

            Asked 2021-Nov-09 at 17:51

            Request more information on this interceptor annotation. Why is the interceptor annotation called @AroundInvoke and not @BeforeInvoke?

            Can I for example invoke an access verification before an action API? What is the guarantee that the Access Verification is completed before the method is actually invoked? Is there something that the VM or the CDI implementation do that does not prevent the actual invocation but execute this interceptor in parallel?

            If I were using the Google Guice AOP Method Interceptors, I am assured that the Access Verification failure will determine whether or not the method invocation BEGINS. How can I assure myself of a similar behavior from the jakarta CDI?

            Have not been able to find this information in the spec

            How to Manage JNDI Context In JUnit Tests?
            Asked 2021-Oct-26 at 15:51

            I'm currently working on writing some tests for a java EE project that uses guice for dependency injection. Dealing with the entity manager and it's datasource has been giving me no end of trouble. I have tried multiple different approaches and they all seem to have a fatal flaw somewhere. I can't seem to figure out how to work with InitialContext without it cross contaminating my tests.

            The key insight was being able to 'reset' the context between tests. Once I had that working, I was able to cleanup my context between tests. Doing that removed the need for mocking out the Context; I could use a real implementation and be confident about the state it was in at the start of each test.

            I believe you are running your browsermob proxy under the latest version of JRE. Since version 16 there are some limitation introduced to the refelction mechanism that make the code that used to work in previous versions not working any more.

            So the easiest solution would be downgrade your JRE. According to this thread, JRE 11 would work for you.

            Wire collection of objects dynamically in Guice
            Asked 2021-Sep-02 at 04:24

            Guice newbie here, with a complicated scenario.

            My company has a large number of constants of a given type (let's call them Thingy) that belong to different teams and are maintained in different parts of our application. However, we need to have a central registry that knows about all of them (let's call this the ThingyService). I am writing a base module that teams can either extend or install, with the purpose of allowing a team to register their Thingys, and giving them access to the ThingyService. This module takes as parameter a list of classes from which I can extract the Thingy constants, this part is working fine.

            What I don't understand is how I can a) make each module know about each other module's list of Thingys and b) how I can create my ThingyService as a singleton that contains all of my Thingys. I have experimented with shared static state and with ThreadLocals, but I keep either breaking tests or breaking my main (play) application. In my naive understanding of Guice, I think I need a MultiBinder for the Thingys, but I don't see how I can share that between modules. Here's what I'd like to do:

            It turns out I omitted one important detail, Thingy has a type parameter, it's actually Thingy, and that's the reason it didn't work before. By cheating and registering Thingy as raw type, and then also injecting it as raw type, I got it to work.
