> We have performances issues on application startup. It takes a while to install all the bundles of a subsystem. After a quick look with JProfiler, we saw that the SpecialZipInputStream.read() was invoked 44 millions times during startup. 
> We're using the Felix framework and the BundleCache.copyStreamToFile calls the method read(byte[] b) from the InputStream. Unfortunately, the method read(byte[] b) and read(byte[] b, int off, int len) are not overriden by the SpecialZipInputStream (thus we don't buffer the read). 
> Completing the decoration in the SpecialZipInputStream solved this problem and divided the startup time by two.
> I've made the pull request with the requested change https://github.com/apache/aries/pull/55
