getNextEvictable throwing an AssertionError

[Maithem]

I'm using the asMap().computeIfAbsent API on the LocalCache and under high concurrency AssertionError is being thrown. The issue also seems to be intermittent.

Cache instantiation

    final Cache<Long, ILogData> readCache = CacheBuilder.newBuilder()
            .maximumSize(5000)
            .expireAfterAccess(30, TimeUnit.SECONDS)
            .expireAfterWrite(30, TimeUnit.SECONDS)
            .recordStats()
            .build();

Usage:

ILogData data = readCache.getIfPresent(address);	
    if (data == null) { 
        final ILogData loadedVal = fetch(address);
        return readCache.asMap().computeIfAbsent(address, (k) -> loadedVal);
    } else {
        return data;
    }
