+- Updated to 1.19 [bsc#1148475, CVE-2019-12402]
+ * ZipFile could get stuck in an infinite loop when parsing ZIP archives
+ with certain strong encryption headers (CVE-2019-12402).
+ * ZipArchiveInputStream and ZipFile will no longer throw an exception if
+ an extra field generally understood by Commons Compress is malformed
+ but rather turn them into UnrecognizedExtraField instances. You can
+ influence the way extra fields are parsed in more detail by using the
+ new getExtraFields(ExtraFieldParsingBehavior) method of ZipArchiveEntry
now.
+ * Some of the ZIP extra fields related to strong encryption will now
+ throw ZipExceptions rather than ArrayIndexOutOfBoundsExceptions in
+ certain cases when used directly. There is no practical difference
+ when they are read via ZipArchiveInputStream or ZipFile.
+ * ParallelScatterZipCreator now writes entries in the same order they have
+ been added to the archive.
+ * ZipArchiveInputStream and ZipFile are more forgiving when parsing extra
+ fields by default now.
+ * TarArchiveInputStream has a new lenient mode that may allow it to read
+ certain broken archives.
+- Rebased patch fix_java_8_compatibility.patch
