The existing code creates the java program and runs it correctly, but it
uses `org-babel-import-elisp-from-file' to interpret the results, and that
sees the bracket and tries to make the response into a list, and errors
when it can't. I don't see a quick fix for it. If you allow unbalanced
brackets but that would be a change in ob-core and would probably cause
unwanted results in other places. If you don't try to convert the output
into a list, you can't present java results as lists or tables.  Really the
problem is that ob-java doesn't support functional mode, so it tries to
guess if scripting mode output should be a table or list.  The version I
wrote supports functional and scripting modes and doesn't use
`org-babel-import-elisp-from-file'.

I would really appreciate that if you are willing, but it's a significant
change (code is 400 lines, 600 lines of tests and test data) and there
might be iterations so you might be signing up for more than you realize.
