Robin Jansohn commented on COMPRESS-340:
----------------------------------------
I'm pretty sure this PR breaks reading empty archive entries. When calling
getNextEntry() and that entry has no content, the code jumps into the first
block at line 830 (SevenZFile.class), clearing the deferredBlockStreams. When
calling entry.read(...) afterwards an IllegalStateException ("No current 7z
entry (call getNextEntry() first).") is thrown. IMHO, there should be another
check for entry.getSize() == 0.
> Provide an efficient way to skip over 7zip entries without decompressing them
