"java.io.EOFException: Truncated ZIP entry: <some entry>"- while extracting a
zip file that contains a entry which lager than 2 GB (Integer#MAX_VALUE)
------------------------------------------------------------------------------------------------------------------------------------------------------
Key: COMPRESS-129
URL: https://issues.apache.org/jira/browse/COMPRESS-129
Project: Commons Compress
Issue Type: Bug
Components: Archivers
Affects Versions: 1.1
Environment: Ubuntu 10; java 6 of sun
Reporter: tinghui wang
Issue:
"java.io.EOFException: Truncated ZIP entry: <some entry>" will be threw while
extracting a zip file that contains a entry with size larger than
Integer#MAX_VALUE bytes (about 2 GB). After the big entry has been read, then
try to get next entry by calling ZipArchiveInputStream#getNextZipEntry(), and
it throws that EOFException.
Cause:
before getting next zip entry, ZipArchiveInputStream tries to close the current
entry and in the close- method it use the field "bytesReadFromStream" to ensure
all entry bytes are read, however the field "bytesReadFromStream" is a integer,
that means it is already overflowed and it leads to a false ensure result.
Solution suggestion:
instead integer using long for "bytesReadFromStream" and possibly for
"readBytesOfEntry" too.
