The error message "commits the instant xxxxxx] error: Bad type on operand stacknull" typically indicates a problem with the Java bytecode that is being executed. This could be due to a variety of reasons such as a bug in the code, a problem with the Java Virtual Machine (JVM), or an issue with the build process.

Here is a plan to understand and resolve the issue:

  1. Identify the exact location of the error: The error message should provide a stack trace that points to the exact line of code where the error occurred. This will help in understanding what operation is causing the error.

  2. Review the code at the error location: The file JavaInsertCommitActionExecutor.java seems to be relevant to the issue. Review the code in this file, especially the execute() method which seems to be involved in the commit operation. Look for any type mismatches or incorrect operations that could be causing the error.

  3. Check the build process: The pom.xml file indicates that this is a Maven project. Check the build process to ensure that the correct versions of Java and other dependencies are being used. Also, ensure that the build process is not corrupting the bytecode in any way.

  4. Test with different JVMs: If possible, test the code with different versions of the JVM. This can help determine if the issue is with a specific version of the JVM.

  5. Debug the code: If the error is still not clear, use a debugger to step through the code and understand what is happening at runtime. This can often provide insights that are not apparent from just reading the code.

  6. Consult the community: If the error is still not resolved, consider reaching out to the Apache Hudi community. As this is an open-source project, there are likely others who have encountered similar issues and may be able to provide assistance.
