Morning,

While working toward openjfx I encountered a problem with the java-icu4j 
package required for antlr4 which openjfx requires. Firstly it's 
building the wrong source - it's trying to build ic4j-*-src.jar which 
only contains the java source suitable for browsing in an ide and is 
thus missing the resource and build files.  So while it creates a 
package that allows compilation to pass it doesn't actually work.

So I tried creating one from the correct source, and for the sake of it, 
using the same version as the existing icu4c package - 66.1[1].  The 
correct java source archive is icu4j-66_1.tgz 
<https://github.com/unicode-org/icu/releases/download/release-66-1/icu4j-66_1.tgz><https://github.com/unicode-org/icu/releases/download/release-66-1/icu4j-66_1.tgz>. 
<https://github.com/unicode-org/icu/releases/download/release-66-1/icu4j-66_1-src.jar> 
I couldn't use githere because the icu git repository requires git lfs.  
My system git doesn't have it so i didn't even try to see if git-fetch 
supports it.

For some reason (unlike icu4c) this is not archived within a single 
subdirectory which causes at least two problems.  First the 
gnu-build-system unpack function changes to the first subdirectory it 
finds after unpacking any archive, which in this case is nothing 
useful.  This can be hacked around by replacing the unpack function or 
adding a post-pack modification to run "cd ..". The second is that you 
cannot apply any patches as the (source (patches --)) function uses an 
entirely different  mechanism to change to the source root subdirectory 
where it simply chooses the first directory entry it finds - which at 
least in this case is a file!  So it fails and aborts.  Of course the 
patches could just be applied as a post-unpack function in the same 
manner as substitute* is often used.

I found this second issue by accident, icu4j doesn't need a patch.

For what it's worth by mid last week I went through this and managed to 
get antlr4 to build (what an awful mess[2]) and have worked out the 
steps for openjfx but it was such a miserable few days of work that I 
went and did other things for a while.  So sorry to say that at this 
point I'm not sure if i'll ever get around to submitting patches for any 
of this.

Regards,
  Z
