Description

I am using camel-cache component in serviceMix. Cache endpoint uri is
"cache://elements?maxElementsInMemory=2&memoryStoreEvictionPolicy=MemoryStoreEvictionPolicy.FIFO&overflowToDisk=false&eternal=false&timeToLiveSeconds=800"

I have 2 bundles (core.jar, services.jar). Inside those bundles I use

@EndpointInject(uri = Constants.CACHE_URI)
ProducerTemplate cacheTemplate;

cacheTemplate.requestBodyAndHeaders(...)

core.jar puts and reads elements from cache.
services.jar only reads elements from cache.

After deploying both bundles it works fine, but if i uninstall services.jar, cache is "destroyed". core.jar (and all others) can't put objects into cache anymore.

How could I make all bundles to "share" the same cache?
