realm-java: Illegal Argument Exception encountered when compressing a Realm file created by version 0.83.0

Hi peeps,

I am currently running into an IllegalArgumentException indicating that the format of the Realm file is invalid when I am trying to call Realm.compactRealm(realmConfiguration...) before I use the realm file.

I have a sample project to demonstrate the crash here: https://github.com/creativepsyco/sample-realm-crash/

Essentially I am trying to compact the realm file before it is ever used in the app.

Steps to reproduce:

Clone the project from https://github.com/creativepsyco/sample-realm-crash/
Compile and run. It will not crash because realm version is 0.82.2
Now in build.gradle edit the version to 0.83.0
Compile and run the app.
It crashes with the stack trace:

Is the SharedGroupManager.compact() implementation compatible with the new format of the Realm File? Right now it seems to be unusable with any Realm created by v0.83 or v0.82.2

I tried to reproduce this issue at our end and it’s not crashing but it crashes in the play store version only on some devices.

Is this possible that if I use deleteRealmIfMigrationIsNeeded() and migration() methods at the same time while creating Realm configuration, it throws this exception “IllegalArgumentException: Illegal Argument: Invalid format of Realm file.”

Also, if I add name() method to create a realm file, will it create a new Realm file with that name or it just renames the previous one. As I am not using name() method right now and Realm creates a file with a default name.

Hope to hear from you soon. Thanks.
