First constructor call of RealmConfiguration.Builder(realmClasses) takes 5+ seconds

[BlueCobold]

How frequently does the bug occur?

Always

Description

Using certain devices, the first constructor call of RealmConfiguration.Builder() takes 5 or more seconds. Consecutive calls within the same process takes just a millisecond. This can be reproduced every time using the same devices. Note that neither a build() is being called, nor a Realm is being opened. Just creating a Builder on itself takes quite long and it does seem to correlate to the number of classes passed.

Stacktrace & log output

Can you reproduce the bug?

Always

Reproduction Steps

Use my schema and call the constructor. I can provide the schema or a minimal app if required.

        val schema = ...
        var t1 = System.currentTimeMillis()
        RealmConfiguration.Builder(schema)
        Log.d(LogTAG, "Init builder: ${System.currentTimeMillis() - t1}") // ~5000 ms
        t1 = System.currentTimeMillis()
        RealmConfiguration.Builder(schema)
        Log.d(LogTAG, "Init builder: ${System.currentTimeMillis() - t1}") // 0 ms
