0 length Ber TLV tag got drop when using BerTlvBuilder

See original GitHub issue

Hi, thanks for your great library. I’ve some issue with building nested BerTLV tag. The following is working as expected :

BerTlv tlv = new BerTlv(new BerTag(0x01),new byte[]{0x06});
BerTlv some = new BerTlvBuilder()
       .addBytes(new BerTag(0xE3), new BerTlvBuilder().addBerTlv(tlv).buildArray())
       .buildTlv();

which gives :

010106
E303010106

But when using 0 length BerTLV tag, the following is not working

BerTlv tlv = new BerTlv(new BerTag(0x01),new byte[]{});
BerTlv some = new BerTlvBuilder()
       .addBytes(new BerTag(0xE3), new BerTlvBuilder().addBerTlv(tlv).buildArray())
       .buildTlv();

I get :

0100
E300

But I’m expecting :

0100
E3020100

Thanks for your help

@bertrandmartel Great. I’ve just release 1.0-8 version. It’ll be available in a hour once sonatype will promote it to maven-central.

I’ve got your point. I thought that you use BerTlvBuilder.buildArray() to create an array.

You are right BerTlvBuilder.buildTlv() returns wrong elements. It skips tags with an empty length.

I’ll fix it.
