Steps & Code to Reproduce

I can’t reproduce it, but crashes are collected from Fabric. According to information from Fabric, this happens when i try to read message id or message content from Realm. Message’s id is encoded as Base58, and Message’s content is a arbitrary strings.

Code Sample

RMessage.java

    public static CMessage toCObject(RMessage rMessage) {
        if(rMessage == null) {
            return null;
        }
        CMessage cMessage = new CMessage();
        cMessage.setCreatedTime(rMessage.getCreatedTime());
        cMessage.setUpdatedTime(rMessage.getUpdatedTime());
        if (rMessage.getAttachments() != null) {
            ArrayList<CAttachment> attachments = new ArrayList<CAttachment>();
            for (RAttachment i : rMessage.getAttachments()) {
                if (i != null) {
                    attachments.add(RAttachment.toCObject(i));
                }
            }
            cMessage.setAttachments(attachments);
        }
        cMessage.setContentType(rMessage.getContentType());
        cMessage.setFrom(rMessage.getFrom());
        cMessage.setId(rMessage.getId());
        cMessage.setContent(rMessage.getContent());
        return cMessage;
    }
