Cannot import binary

[dukebarman]

$ ~/.local/bin/bjoern-import /bin/true
Project created.
File uploaded.
{
  "errors": [{
      "code": 505,
      "reason": 505,
      "content": "java.lang.NoClassDefFoundError: octopus/lib/structures/OctopusNodeProperties"
      }
  ]
}

And processes of radare2 don't close:

$ ps -e
...
109649 ?        00:00:00 radare2
109687 ?        00:00:00 radare2
109741 ?        00:00:01 konsole
109745 pts/1    00:00:00 zsh
109777 ?        00:00:00 radare2
109793 pts/1    00:00:00 ps

It is from my earlier attempts with other binaries

After reboot and new commit works. Maybe a lot of radare2 processes were the cause (But why they didn't close after get a error?)
