Hi,

Yesterday I tried to install from the beginnig a working basex
environnement on another repertory, just to do some tests. BaseX has
been installed form the zip.

After adding additionnal repos, this error occured on the new install
with basexhttp on. After stopping it, I launched the older install to
verify what was going wrong, and now the same error occurs on this one too.

I am not very familiar with java, do you know what could posssibly be
wrong here ?

Regards

Guillaume
