Realm doesn't work with SLF4J? - realm

Question

We wanted to integrate Realm in our app, and we encountered following problem:

Where StaticLoggerBinder looks like:
public class StaticLoggerBinder implements LoggerFactoryBinder {
private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();
private static final String loggerFactoryClassStr = AndroidCustomLoggerFactory.class.getName();
private final ILoggerFactory loggerFactory = new AndroidCustomLoggerFactory();
private StaticLoggerBinder() {
}
public static final StaticLoggerBinder getSingleton() {
return SINGLETON; // line 27
}
public ILoggerFactory getLoggerFactory() { //line 30
return this.loggerFactory;
}
public String getLoggerFactoryClassStr() {
return loggerFactoryClassStr;
}
}
From my understanding, problem is probably with Realm's transformer. It wants to include some unknown logger to our code. Main problem with our app is, that we have some 3rd party library, that uses also SLF4J, and we can't modify it. I tried with 0.90.1 version, while SLF4J used by 3rd party library is in 1.6.4 version. Dexguard is 7.1.26.
Also, note that, Realm works with my environment and another project with same dependencies except this 3rd party library and SLF4J.
List of dependencies:
plugins:
apply plugin: 'com.android.library'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'dexguard'
apply plugin: 'realm-android'
dependencies:
provided 'javax.annotation:jsr250-api:1.0'
apt 'com.google.dagger:dagger-compiler:2.0.2'
compile([
'com.google.dagger:dagger:2.0.2',
'com.mcxiaoke.volley:library:1.0.18',
'com.google.code.gson:gson:2.3.1',
'io.reactivex:rxjava:1.0.11',
'io.reactivex:rxandroid:0.24.0',
'com.jakewharton.timber:timber:3.1.0',
'com.squareup.okhttp:okhttp:2.6.0',
'com.squareup.okio:okio:1.6.0',
'com.android.support:support-v4:22.1.1'
])
compile files('libs/libconceal.jar')
compile files('libs/conceal_android.jar')
compile files('../dexguard/dexguard-runtime.jar')
compile files('libs/slf4j-api-1.6.4.jar')
compile files('libs/lib3rdparty.jar')
retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:2.3.0'
Is this possible, that Realm mess up here with that implementation? Is there any way to prevent it?
