Major Description
This ticket proposes to upgrade Spark's use of Janino from 3.0.9 to 3.0.10.
Note that 3.0.10 is a out-of-band release specifically for fixing an integer overflow issue in Janino's ClassFile reader. It is otherwise exactly the same as 3.0.9, so it's a low risk and compatible upgrade.
The integer overflow issue affects Spark SQL's codegen stats collection: when a generated Class file is huge, especially when the constant pool size is above Short.MAX_VALUE, Janino's ClassFile reader will throw an exception when Spark wants to parse the generated Class file to collect stats. So we'll miss the stats of some huge Class files.
The Janino fix is tracked by this issue: https://github.com/janino-compiler/janino/issues/58
