[jrodbx]

what version are you using? I think this should be fixed on master with https://github.com/cashapp/paparazzi/pull/530, but it's unreleased, so I'd like to confirm whether there's work to be done here, or if this can be closed out.

[sobaya-0141]

I am using version 1.0.0

I believe this problem is occurring with a specific Java distribution. Because it occurred with Zulu18.32 and not with Temurin-18.0.2.1+1.

[jrodbx]

Mind confirming the issue?

We are seeing a similar regression in Paparazzi as of this weekend. Reverting to a previous snapshot of Paparazzi did not resolve the issue for us but reverting to v1.0.0 did resolve it.

@DavidBrunow 1.0.0 is the newest version of Paparazzi no? Did you mean something else?

I am also getting this error, and I tried with Temurin-18.0.2.1+1 and 19.

Seeing this as well

Based on this answer there's workaround yet for Java 18+. However, following the future of the commit mentioned in #205's comment, they migrated to using Unsafe in https://github.com/powermock/powermock/pull/1026 which may or may not work on Java 18 and 19.

As a workaround, you can try to set your Test task's toolchain to something lower:

tasks.withType(Test).configureEach {
    javaLauncher = javaToolchains.launcherFor {
        languageVersion = JavaLanguageVersion.of(11)
    }
}

Thanks, this has fixed the modifiers error, but now I get

 kotlin.UninitializedPropertyAccessException: lateinit property sessionParamsBuilder has not been initialized

Seems to be just locally (macOS). On our CI with the same java it works.

[TWiStErRob]

Note, there might be a better workaround than toolchains: https://github.com/cashapp/paparazzi/pull/1030/files

Re sessionParamsBuilder, https://github.com/cashapp/paparazzi/issues/486 looks related, but not necessarily the same problem. If that doesn't help, please consider opening a separate issue to keep this one focused on modifiers.
