Overview
This article explains the common causes of this error and offers troubleshooting ideas and solutions.
Symptoms
If a subjob (what is a subjob?) has too many components or if there are too many columns in the schema, the Talend Job may fail to compile, and produce the following exception:
|
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The code of method tFileInputDelimited_1Process(Map<String,Object>) is exceeding the 65535 bytes limit
|
This is because Talend Studio is a code generator and creates Java code for each Talend Job. Each subjob is a method in the Job class, If a subjob is too big, the size of the final generated code will exceed 65536 bytes.
According to Java specifications, the amount of code for this non-native, non-abstract method is limited to a size of 65536 bytes, so the generated code of a subjob cannot be greater than this limit.
Procedure
As a workaround, optimize the Job to reduce the size of the final generated code of a subjob. Try the following:
- Minimize the number of components in the subjob, especially debugging components such as tLogRow.
- Divide the subjob to several subjobs,
