How frequently does the bug occur?

Sometimes

Description

I am setting the default config of Realm DB as follows :

class RealmDB : Application() {
    override fun onCreate() {
        super.onCreate()
        try {
            Log.i(TAG, "Setting RealmDB Default config")
            Realm.init(this)
            val config = RealmConfiguration.Builder()
                .allowWritesOnUiThread(true)
                .allowQueriesOnUiThread(true)
                .deleteRealmIfMigrationNeeded()
                .build()
            Realm.setDefaultConfiguration(config)
        } catch (ex : IOException){
            Log.e(TAG, "Setting RealmConfiguration failed.")
        }
    }
}

Then I am trying to get the default instance in my app as follows: Realm.getDefaultInstance()

But a Permission denied exception is thrown sometimes. The strange thing is that, this exception is thrown randomly. Sometimes, the realm instance is created successfully, but sometimes it fails with the exception.

[rorbech]

This is an issue for Realm Java so transferring it.

@LakshmiTeja17 Could you elaborate a bit more on the setup. Is this a system app and/or other observations that could help us identify the root. Maybe also the full stack trace?
