Subject [Bug 60140] New: OOM caused by Memory Leak in FileBackedDataSource

            Bug ID: 60140
           Summary: OOM caused by Memory Leak in FileBackedDataSource
           Product: POI
           Version: 3.15-dev
          Hardware: PC
            Status: NEW
          Severity: major
          Priority: P2
         Component: POIFS
          Assignee: dev@poi.apache.org
          Reporter: lfcnassif@gmail.com

Investigating TIKA-2058, we discovered HeapByteBuffers are being cached
unnecessarily into buffersToClean, because they need no special unmapping, when
datasource is not writable.

A single instance of FileBackedDataSource consumed 5.7GB of heap, triggering
OOM.

More details on https://issues.apache.org/jira/browse/TIKA-2058

Patch will be attached.
