I have stared at "consoleFull" a few minutes without spotting anything suspicious.

In Isabelle/38528017e4c8 there is some more verbosity, to see where it gets
stuck --- if it is repeatable at all.

Note that I did manage to build Isabelle + AFP with pdf + HTML several times
on other big machines, using settings like this:

  ISABELLE_TOOL_JAVA_OPTIONS="-Djava.awt.headless=true -Xms1g -Xmx8g -Xss16m"

  ML_OPTIONS="--minheap 1500"
