In mongoDB I want to get a result in order, but when I use the sort method, the Error
com.mongodb.MongoQueryException: Query failed with error code 96 and

public MongoCursor<Document> getAllDateRWDByTowerId(Integer towerId) {
MongoCollection<Document> mongoCollection = mongoTemplate.getCollection("rwd");
FindIterable<Document> findIterable = collection.find().sort(Sorts.orderBy(Sorts.descending("date")));
return fi.iterator();
}
I attempt some different methods, the same error always happen.I don't know why it happened and how to resolve this problem.
The error is:
Sort operation used more than the maximum 33554432 bytes of RAM
Mongo Sort Operations:
If MongoDB cannot use an index to get documents in the requested sort
order, the combined size of all documents in the sort operation, plus
a small overhead, must be less than 32 megabytes.
The solution would be to add an index to the sort field. See here for more details.
You should try to add a index for object's field "date" ,
if you don't add it , mongo will load a lot of data from harddisk in memory
and cause a exception.
if you know index , in some database index was implement by B+ data struct，
it's a hard-disk friendly data struct ，use less memory.

The only reason for NPE if it happens at the line of code you mentioned above is serviceTask is null.
If you're not using the correct test runner which can help you to initialise the mock instance, then you can actually initialise them manually in your setUp method by using MockitoAnnotations.initMocks(this);
But if you already did so or used the correct test runner, then probably you linked to a wrong line of code. Try to debug yourself again.
Your stack trace doesn't look like it caused from your linked line of code.
I am using Java + Spring boot(Ver 2.1.16) + Hibernate + JPA for an API project.
I have several models with several OneToMany relationships.
I haven't mentioned a fetch type but as I know it's Eager in default according to my used Hibernate version.
I have mentioned #Transactional in my service method also.
All good when I get data calling to the API endpoint via Postman (I receive all fields including OneToMany) without any exception.
But when I call the service method via Unit tests, I get following exception.

What can be the issue?
When you call the rest API using postman, it works because Spring Boot offers a feature called OpenSessionInViewFilter which open a hibernate session for the current session of your HTTP request. When you call the service method directly by the test method without being annotated by #Transactional, the lazy fetching does not work because there is no hibernate session opened.
I could resolve the issue after adding
#Transactional
to my Test methods also

I don't know how to tell the compiler that getExceptionHandler() doesn't exist any more.
Thanks
The problem is not in your test! The test calls ISOPPCServiceHelper which still uses the method getExceptionHandler(). You have to recompile that class. Always use clean test of your build system after refactorings to make sure everything is compiled right (hopefully you have one, otherwise rebuild project of your IDE should do the job).
In Java I am using FutureTask to run a Callable asynchronously via Executor. In order to check if an error occurred from the calling thread, I need to throw potential exceptions from the Callable. This however, leads to the stacktrace printed out to System.out (I debugged and this happens inside Unsafe.unpark(Thread) from LockSupport.unpark(Thread)).
Any ideas how I could prevent this?
I already log the exception to a real logger before (via SLF4J) and never want direct stacktraces on System.out.
Update: I think I already pointed out the relevant information but to clarify all the questions:
This test case can reproduce the Problem (Method testTransferStreamAsyncCallbackFail()):
https://github.com/m-m-m/util/blob/master/io/src/test/java/net/sf/mmm/util/io/base/StreamUtilTest.java
The implementation used is this:
public AsyncTransferrer transferAsync(InputStream inStream, OutputStream outStream, boolean keepOutStreamOpen, TransferCallback callback) {
StreamTransferrer transferrer = new StreamTransferrer(inStream, outStream, keepOutStreamOpen, callback);
AsyncTransferrerImpl task = new AsyncTransferrerImpl(transferrer);
this.executor.execute(task);
return task;
}
I debugged through the eniter code and it is definetly not my code that logs to the console. This is done in the JDK as I tried to explain.
Additional Update to answer the questions:
The executor I am using is Executors.defaultThreadFactory()
As you can see here:
https://github.com/m-m-m/util/blob/master/core/src/main/java/net/sf/mmm/util/concurrent/base/SimpleExecutor.java#L30
https://github.com/m-m-m/util/blob/master/io/src/main/java/net/sf/mmm/util/io/base/StreamUtilImpl.java#L165
The output is the stacktrace of the Exception that I throw in my test from the Callable:
java.util.concurrent.ExecutionException: net.sf.mmm.util.io.api.RuntimeIoException: IO: An unexpetected error has occurred while copying data!
