ToralfNiebuhr opened a new issue, #1051:
URL: https://github.com/apache/poi/issues/1051
If I create a new HSSFWorkbook without a template.
Like
`HSSFWorkbook wb = new HSSFWorkbook();
wb.write(new FileOutputStream("testfile"));`
Then, all versions above "5.0.1" create this warning
`08:38:09,198 WARN POIDocument - DocumentSummaryInformation property set
came back as null
08:38:09,205 WARN POIDocument - SummaryInformation property set came back
as null`
The cause is, that when "getBytes()" is called; then
[updateEncryptionInfo](https://github.com/apache/poi/blob/e6a04b49211e23c704fcdbe524d99d2f4486b083/poi/src/main/java/org/apache/poi/hssf/usermodel/HSSFWorkbook.java#L2436-L2438)
calls `readProperties()` from an empty POIDocument. The missing Records are
only added later in getBytes(), when they are read from the internal wb.
I don't know what the correct fix is here. Replace `readProperties()` with
`readProperties(false)` (same behavior as in older versions)
Or, updateEncryptionInfo working agains the wb, or calling
updateEncryptionInfo later.
