Work Description: kennknowles opened a new pull request #7099:
[BEAM-6104] Use a very large stack for compiling Beam
URL: https://github.com/apache/beam/pull/7099
This seems to alleviate occasional pain from stack overflows in javac when
compiling generated SQL parsing code. I had assumed it was an accidental
infinite recursion, but it is actually just extremely deep nesting in the
generated code, which has 500+ deep nested conditionals.
