I had some extra time today, so I took a look at ob-java.el. Unless
header argument dir is set, java is run in a temporary directory. So I
can get around this problem by setting header argument

:dir "."

which is nice, at least as a workaround.

I am not sure what the default behaviour should be. At the moment,
though, I do not think temporary dir is a good default, because by
default the program will then the "miss" all opened (data) files as
well. Right?

Perhaps all babel languages have a common policy here that I am not
aware of.

But in any case it looks to me that the behaviour has changed now, so if
it is changed in the stable branch (I am running master), I think it
should be documented clearly (as an incompatible change). Perhaps it
already is documented like that.

All the best, and stay safe.
