If I studied code well, I thing that there is bad key put as a parameter, below is fixed method getContext. Please check if the fix is ok. private Context getContext(final Properties env, final String key) throws NamingContextException { final Context context = getFreeContext(key) ; if (context != null) { return context ; } if (numContexts == POOL_SIZE) { if (freeContextOrder.size() == 0) { return null ; } final Iterator<Entry<Context, String>> freeContextIter = freeContextOrder.entrySet().iterator() ; final Entry<Context, String> freeContextEntry = freeContextIter.next() ; final Context freeContext = freeContextEntry.getKey() ; final String freeContextKey = freeContextEntry.getValue() ; if (LOGGER.isDebugEnabled()) { LOGGER.debug("Ejecting Naming Context from pool, key: " + freeContextKey) ; } freeContextOrder.remove(freeContext) ; final List<Context> contexts = freeContexts.get(freeContextKey) ; // FIXED KEY contexts.remove(freeContext) ; if (contexts.size() == 0) { freeContexts.remove(freeContextKey) ; // FIXED KEY } numContexts-- ; closeContext(freeContext) ; } return createContext(env, key) ; }
