> Resolve JVM bytecode size limit exceeded in <init> method due to excessive
> field initializations in SQL job
> -----------------------------------------------------------------------------------------------------------
>
> Key: FLINK-37289
> URL: https://issues.apache.org/jira/browse/FLINK-37289
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.16.1
> Reporter: Xinglong Wang
> Priority: Major
> Labels: pull-request-available
>
> h3. Problem Description
> The SQL job encounters issues due to having too many fields in the DML
> operations, such as a job which has over 2,000 fields. This results in the
> code generation process creating an initialization block that needs to
> initialize these fields and some auxiliary intermediate variables, totaling
> over 20,000 members. Consequently, the bytecode for the {{<init>}} method
> exceeds the JVM's single method limit of 64KB, resulting in the following
> error:
> {code:java}
> Caused by: org.codehaus.janino.InternalCompilerException: Compiling
> "StreamExecCalc$127849": Code of method
> "<init>([Ljava/lang/Object;Lorg/apache/flink/streaming/runtime/tasks/StreamTask;Lorg/apache/flink/streaming/api/graph/StreamConfig;Lorg/apache/flink/streaming/api/operators/Output;Lorg/apache/flink/streaming/runtime/tasks/ProcessingTimeService;)V"

> h3. Explanation of the {{<init>}} Method
> * {*}{{<init>}} Method{*}: In Java bytecode, each constructor is represented
> as a special method named {{{}<init>{}}}.
> * {*}Order of Instance Initialization{*}: The Java compiler weaves the
> initialization logic into the {{<init>}} method in the following order:
> ** a. Calls the superclass constructor (calls the default no-argument
> constructor if none is explicitly called).
> ** b. Initializes instance variables.
> ** c. Executes instance initialization blocks.
> ** d. Executes the actual code of the constructor.
> * {*}Bytecode Generation{*}: The compiler inserts all this initialization
> logic (instance variable initialization and instance initialization blocks)
> into the beginning of the {{<init>}} method, after the call to the superclass
> constructor but before the constructor's own code.
> * {*}Impact on {{<init>}} Method Size{*}: Therefore, even if the constructor
> itself has little code, having a large number of instance variable
> initializations or complex instance initialization blocks will increase the
> bytecode size of the {{<init>}} method.
> h3. Fix
> The initial logic in the initialization block, when translated into bytecode,
> is executed via {{putfield}} instructions. The solution is to segment the
> numerous {{putfield}} instructions into smaller blocks. For example, group
> every 1,000 initialization statements into a private method, then call these
> private methods within the initialization block. This transforms the
> initialization block into a series of {{invokespecial}} instructions, which
> are fewer in number.
