JDK-6595845 - Java 6 JavaWebstart increases footprint by factor 2
Description
ZipFile retains instances of Inflater for longer than is necessary, each of which consumes a fair amount of memory.  See description for 6595845.  Part of that fix is to decrease the memory used by ZipFile in retaining instances of Inflater which are no longer used.
Comments
EVALUATION In ZipFile.java, Inflater.reset() is invoked when get Inflater is called. This unnecessarily delays release of resources held by Inflater instances, which could be released in ZipFile.releaseInflater().
