​Oracle Java provides a way to debug the JVM externally as described:

I successfully managed to debug Zotero's Java based extension on Ubuntu
16.10 running LibreOffice 5.3.0.3 with JDK 1.8.0_121 by following
https://help.libreoffice.org/Common/Start_Parameters and connecting via
Eclipse. Note that I've started working with LO and Zotero extensions
without any prior LO development experience this week, so I am mostly
shooting in the dark here. Excuse my uninformedness. On Ubuntu the JVM with
the debugging server is initialized when I click one of the extension
buttons, which supposedly starts up JVM in LO as the extension is Java
based.
