Summary: PATCH: OpenXML4j OPCPackage calls
Runtime.getRuntime().gc() which is considered a
perfomance bottleneck
Product: POI
Version: 3.5-FINAL
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: POI Overall

OpenXML4j causes a lot of unnecessary garbage collection on our system
which leads to performace losses.
Apparently, according to the latest JavaDoc [1], a call to
Runtime.getRuntime().gc() causes a full heap garbage collect, which
isn't what you usually want in any longer running application. The
runtime knows when to garbage collect.
