Infinispan cannot put inner classes to write-behind cache --------------------------------------------------------- Key: ISPN-4067 URL: https://issues.jboss.org/browse/ISPN-4067 Project: Infinispan Issue Type: Bug Components: Marshalling Affects Versions: 6.0.0.Final Environment: JDK 1.7_45 Reporter: Stanislav Ivanov Assignee: Dan Berindei Priority: Minor Infinispan throws NotSerializableException when trying to put inner class to write-behind cache. Here is the example: {code:title=class which I want to store in cache (actually, it's inside the other class)|borderStyle=solid} final class PojoCoder implements Serializable { private static final long serialVersionUID = -6238699065180988597L; private String name_; private String favouriteLanguage_; PojoCoder(String name, String favouriteLanguage) { name_ = name; favouriteLanguage_ = favouriteLanguage; } @Override public String toString() { return name_ + " loves " + favouriteLanguage_; } public String getFavouriteLanguage() { return favouriteLanguage_; } public String getName() { return name_; } } {code} {code:title=cache config|borderStyle=solid} final EmbeddedCacheManager cacheManager = new DefaultCacheManager(); cacheManager.defineConfiguration(CACHE_NAME, new ConfigurationBuilder() .eviction() .maxEntries(2) .persistence() .passivation(false) .addSingleFileStore() .location(tmpStoragePath) .maxEntries(6) .build()); {code} {code:title=code that fails|borderStyle=solid} final Cache<String, PojoCoder> testCache = cacheManager.getCache(CACHE_NAME); testCache.put("alex", new PojoCoder("django-lover alex", "Python")); //NotSerializableException on this line {code} Actually, stack trace tells something about problem with *this* reference. Unfortunatelly, I don't have time to investigate deeper this issue - inner class was created just for test, normally I would store typical outer classes.
