Bug #: 51903
Summary: [PATCH] RevisionMarkAuthorTable Illegal Length -1
getFromUnicodeLE
Product: POI
Version: 3.8-dev
Platform: PC
Status: NEW
Severity: major
Priority: P2
Component: HWPF

Patch for issue
Sporadic bug with some Word files (unable to submit sample due to sensitive
nature of files).
The LittleEndian.getShort sometimes returns a length of -1, which causes a
failure in subsequent getFromUnicodeLE() call. Added a check for invalid
length before proceeding. Was last entry in my test file and having a null
entries array value does not appear to cause any additional errors down-stream.
Stack Trace (POI version 3.8-beta4)
Caused by: java.lang.IllegalArgumentException: Illegal length -1
