Fix for biglybt not launching after update to version 4.0.0.0

[AzaleeBleue]

Hi,

It's not an issue with this repo, but it can be useful to keep this small doc until a fixed biglybt release is available.

BiglyBT 4.0.0.0 has a bug where it may not launch when not using a clean profile.
It was my case when updating in my container, not sure if it's impacting everyone with an existing profile.

As said here: BiglySoftware/BiglyBT#3654 (comment), it's fixed in BiglyBT v4.0.0.1-beta02.

Here is how to replace the 4.0.0.0 jar with the fixed one in a running container.
You need to have an access to the shell in the container (through running a terminal in vnc, or docker container exec).

1. Kill currently running biglybt process
   Change the process id in the kill command with the one given by running the first command.

$ ps -ef | grep bigly | grep java
root      4325  4202 99 15:26 ?        00:00:36 java -Xmx256m -cp ./BiglyBT.jar:./commons-cli.jar:swt/J17/swt-x86_64.jar -Djava.library.path=/opt/biglybt -Dazureus.install.path=/opt/biglybt -Dazureus.script=/opt/biglybt/biglybt -Dazureus.script.version=12 -Xmx2g --add-opens java.base/java.net=ALL-UNNAMED com.biglybt.ui.Main

$ kill -9 4325

2. Download BiglyBT v4.0.0.1-beta02
   URL is from the biglybt issue linked previously.

$ cd ~

$ wget https://biglybt-files.s3.us-east-1.amazonaws.com/core/BiglyBT4001-B02-signed.jar

$ cp BiglyBT4001-B02-signed.jar /opt/biglybt/BiglyBT.jar

3. Start biglybt
   From vnc because I don't know how to launch it from a docker container exec shell and having biglybt interface visible through vnc.
