biglybt missing the gudy directory (bouncycastle crypto compat files)

Bug #1965091 reported by Fizzfadlt
This bug affects 1 person
Affects Status Importance Assigned to Milestone
biglybt (Ubuntu)

Bug Description

biglybt has an org/gudy directory for compatibility with BouncyCastle crypto, see

The rest of the org subdirectory actually exists in the jars provided in the package, but not the org/gudy directory.
Note that bouncycastle (libbcprov-java) does not provide that directory, and it's supposed to come from biglybt.

The ubuntu package provides two actual jar files (/usr/share/java/biglybt-core.jar and /usr/share/java/biglybt-ui.jar) I checked both of them for the appropriate class files and they're definitely missing.

See end of this bug for entries from log showing class not found errors.

I examined the jars and verified these files are missing from biglybt version (default for 21.10/impish) and biglybt version (jammy)

I'm not sure if this is preventing crypto from actually working, but I'm getting tons of crashes/hangs and going through what I see in log/posting bugs in the hopes that fixes them.

Get tons of log entries like:
