Getting IllegalStateException while calling restTemplate.exchange()

Getting the java.lang.IllegalStateException while trying to read the data from json file using RestTemplate.exchange(). Tried many ways, but no success. Any suggestion would be appreciate.
Code:
ResponseEntity<GetCustomerResponse> customerResponse = restTemplate.exchange("J:\Backup\FILWORKSPACE\tapp100997_accountopeningservice\target\classes\testdata\CustomerEnquiryApiResponse.json",HttpMethod.POST, request, GetCustomerResponse.class);
Exception :

how to handle nested #DynamoDBDocument

I have a domain called UserAdvice which has a variable of type PriceWithPaf, which has 2 variables in it, which are again of custom-type/class-object. I have declared both the inner-objects/variables and the parent class which is a variable in the Domain as #DynamoDBDocument.
The best part is I am able to save the data exactly the way I want in DynamoDB Database but when I read the data back to object I get following error:
(I am using spring data for dynamoDB - from github & this error is shown in test case - where I use AmazonDynamoDBLocal)

After facing this issue and trying to solve it for 3 days. Finally came across this article , it worked .
My mistake was :
Initial
#DynamoDBAttribute
public String getPeriod() {
return period;
}
public void set_period(String period) {
this.period = period;
}
Changed it to :
#DynamoDBAttribute
public String getPeriod() {
return period;
}
public void setPeriod(String period) {
this.period = period;
}

It worked - the error was due to wrong getter setup - one of the getter was suppose to return custom object (PriceWithPaf) instead of returning a double.
This made the unmapping of dynamoDBDocument go wrong.
using DynamoDBDocument is easy - just put this annotation on all the class which acts as a variable to the Domain Class. and make sure your getter and setter are default/not manipulated ;)

org.mockito.exceptions.misusing.WrongTypeOfReturnValue: ArrayList cannot be returned by toString()

In my code i set the return value of a mock:
when(spreadSheetHandler.readData("2"))
.thenReturn(jsonUtility.fromSpreadSheetJsonFile());
this is readData signature
public List<List<String>> readData(String range) throws IOException {
and this is
public List<List<String>> fromSpreadSheetJsonFile() {
List<List<String>> fromJsonFile = null;
ObjectMapper mapper = new ObjectMapper();
TypeReference<List<List<String>>> mapType = new TypeReference<List<List<String>>>() {};
try {
fromJsonFile = mapper.readValue(new File("/Users/eladb/WorkspaceQa/sdk-service/src/test/resources/spreadsheetList.json"), mapType);
} catch (Exception ex) {
logger.error("json parsing failure", ex);
}
return fromJsonFile;
}
fromSpreadSheetJsonFile finishes successfully
but then i get an error:

If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception *might* occur in wrongly written multi-threaded tests.
Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies -
- with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.

what can cause it? as i return List> as expected?

Hibernate create a copy of entity in listener

In my application I have an instance of A, when I update Ai, I want to create a copy of Ai with all previous values and insert that.
To do this work, I made a PreUpdateEventListener and in the onPreUpdate method, I want to create that clone, and then save it as a new instance, so assign Id:0 and then treat it as a new insertion.
To do that, I've:
from the SessionFactory, I opened a new Session
from that new session, using the Ai identifier, I've loaded the instance with previous state
I closed the newly created session
then I created a new instance, the clone, and then I copied into all the values treating associations so they could be treated as new ones
then I saved the new instance, the clone, in the current session
Everything seems to work, but when my code calls the flush (the caller code) I get a fantastic:

Iterating through large ResultSets closes my JTDS connection

I'm writing code whose purpose is to read all records from two not-so-small tables. Table A has about 500k records and 25 columns, and Table B has a little under 200k records and 143 columns.
The tables are located on two separate SQL Server 2008 databases and I have no trouble establishing a connection to them. I use jtds-1.3.1.jar as my JDBC Driver. The problem is that I always get an exception before I can read all their records, and the exception varies between
java.sql.SQLException: I/O Error: socket closed
and
java.sql.SQLException: I/O Error: Stream 2 attempting to read when no request has been sent
These exceptions always happen after reading about 69k records from Table A or 12.5k records from Table B.
My connection String is:
jdbc:jtds:sqlserver://host:port;databaseName=XXX;user=XXX;password=XXX;useCursors=true;charset=ISO-8859-1
My code:
Statement st = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
st.setFetchDirection(ResultSet.FETCH_FORWARD);
st.setFetchSize(100);
ResultSet rs = st.executeQuery("SELECT * FROM TABLE A");
int counter = 0;
while (rs.next()) {
counter++;
if (counter % 2000 == 0) {
System.out.println(counter + " records.");
}
}
The first exception:
java.sql.SQLException: I/O Error: socket closed

I've searched a lot but only found questions regarding authentication issues or invalid data that the driver couldn't parse, which I believe it's not the case here. Is there anything obvious I'm missing?
Any inputs will be highly appreciated.
