[8.51a problem]CRC error when unpacking file

[BeckYang]

I have a special zip file created by zip4j (http://www.lingala.net/zip4j/)
It could be unpacked/testing by many software (7z v9.2.0, jar.exe of JRE...)
But when I unpack/test it using TC 8.51a, a error message "CRC error, archive fiel corrupted!" is displayed. Other zip files created by zip4j do NOT have such problem.

Please investigate the problem, thank you.

The zip file and original file(data.bin) could be download from http://www.mediafire.com/download/6a8h6y54tednoh1/tc_851a_unpack_problem.zip.
(Test.java and Test.class are test program, JRE and net.lingala.zip4j_1.3.2.jar are required to run it)

There is no problem with this zip file
Tested with TC 8.51a x64 and x86

The inner zip file zip4j_output.zip does give me an error here.

I have checked it - there are 3 extra bytes before the ZIP crc header "PK"07 08, so TC cannot find the CRC after the file. I don't know how other ZIP packers manage to handle this file, but it's definitely not standard ZIP.

For me only the test function gives an error but I can open this inner zip without any error.

I can open this inner zip without any error.

Try to extract data.bin

I try to unpack the file using "jar xvf zip4j_output.zip" and get errors too.
(Execute "jar tvf zip4j_output.zip" does not display any error... )

Maybe it's a issue of zip4j... I have report this case to them, thank you.
