Kenneth Knowles commented on BEAM-6025:
---------------------------------------
The generated code for the parser has a tremendous amount of nested blocks. In
turn, Javac's recursive descent parser does what recursive descent parsers do
best - overflow. Both of these are not feasible to change, so the only solution
is to crank up the limits, which I did in
https://github.com/apache/beam/pull/7099.
