Description

Version : ehcache-1.4.1

I was wondering why my caches we not flushed to disk and found out that my Cache Elements contained Collections with null values which are not considered as Serializable by EHCache …

In Element.java:498 : public final boolean isSerializable() { return key instanceof Serializable && value instanceof Serializable; }

The problem is that null instanceof Serializable returns false although null can be serialized.

I changed that to :

public final boolean isSerializable() {
    return key instanceof Serializable && ((value == null) || (value instanceof Serializable));
}

And it works fine now. Sourceforge Ticket ID: 2026586 - Opened By: balb - 24 Jul 2008 09:38 UTC
