-------------------------------------------------------------------
[~julianhyde] the upstream issue in Janino was
[fixed|https://github.com/janino-compiler/janino/commit/e2ac8b9efa3b22efd01ade45cae35ea3ffb24b35].
Seems as if they are willing to provide a new Janino release soon.
Our extensive unit test suite for our Calcite-based code is green again,
including tests which triggered the earlier Janino bug.
As this is quite a critical regression for Calcite, could you schedule a new
release soon?

> Janino upgrade breaks SELECTs with many projects causing JVM crashes

> Key: CALCITE-5227
> URL: https://issues.apache.org/jira/browse/CALCITE-5227
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.30.0
> Reporter: Daniel Glöckner
> Priority: Critical
>
> In our case we have SELECTs with > 1000 project fields. You might say this is
> a bit crazy but this is how our data model looks like ;)
> We recently upgraded to Calcite 1.30 and noticed JVM crashes for such
> SELECTs.
> After thorough analysis we found that the byte code produced by newer Janino
> versions is 350 times larger compared to the byte code produced by javac.
> I created a unit test to reproduce the issue in Calcite code base:
> https://github.com/apache/calcite/commit/f4d4815dff5537c56b34b36794c71d7a9829eec6
> The Janino issue is tracked here:
