# lz4-java v1.3.0 introduced usage of sun.misc.Unsafe, which would later become
# depricated in jdk 9 and kept as an unexposed API in later jdk releases.
# lz4-java optionally uses Unsafe to achieve faster compression and decompression,
# however it's implementation is not critical to functionality, and can be removed.
Patch0:        0-remove-unsafe.patch
# After updating mvel to version 2.4.10, MVEL generated classes have formatting issues where
# code after comments are not being formatted with new lines. As a result, including comments
# in the templates results in classes with invalid code following the first comment.
# This patch simply removes comments from the templates so the classes can be generated as expected.
# Related bug: https://github.com/mvel/mvel/issues/152
Patch1:        1-remove-comments-from-templates.patch
# Adds a simple makefile to be run in-place of the cpptasks in the build.xml
Patch2:        2-remove-cpptasks.patch
# some lz4-java tests require randomizedtesting, which is not currently
# shipped or maintained in Fedora; remove those and use system ant-junit to run applicable tests
Patch3:        3-remove-randomizedtesting-tests.patch
# RHSCL: condition doesn't support the nested "javaversion" element
Patch4:        4-remove-javaversion.patch
# RHSCL: build missing lz4 and xxhash libs required for liblz4-java.so
Patch5:        5-build-libs.patch

%description
LZ4 compression for Java, based on Yann Collet's work.
This library provides access to two compression methods
that both generate a valid LZ4 stream:

* fast scan (LZ4):
    ° low memory footprint (~ 16 KB),
    ° very fast (fast scan with skipping heuristics in case the
      input looks incompressible),
    ° reasonable compression ratio (depending on the
      redundancy of the input).
* high compression (LZ4 HC):
    ° medium memory footprint (~ 256 KB),
    ° rather slow (~ 10 times slower than LZ4),
    ° good compression ratio (depending on the size and
      the redundancy of the input).

The streams produced by those 2 compression algorithms use the
same compression format, are very fast to decompress and can be
decompressed by the same decompressor instance.
