Spring batch 3600 partitions long pause before starting

I have the following spring batch job with a partitioned step that creates 3600 partitions for a partitioned step. I use a ThreadPoolTaskExecutor with a max pool size 100 and a queue capacity of 100 (although it seems to make no difference for speed). Im using Visual VM to monitor the threads and I notice the taskExecutor threads don't start until > 5 minutes after starting the job.
Oddly enough, If I limit the number of partitions to 100 the threads start fairly quickly and finish in about a minute.
Another issue I notice is that there doesn't seem to be more than one database connection ever as seen in the VisualVM thread visualization
Can someone please review my batch job below and tell me if I am missing something that would limit the number of database connections to 1? Also, why would adding more partitions affect the performance if my ThreadPoolTaskExecutor parameters don't change? Shouldn't the jobs just sit in a queue until there is a thread able to service them?

The time to create partitions depends on the performance of your ReservationPartitioner as well as the number of partitions. Creating 3600 partitions means creating 3600 StepExecution/ExecutionContext objects and persisting them in the corresponding tables. This can take time for such a high number of partitions.
In regards to the database connection, you are using the MapJobRepositoryFactoryBean with a ResourcelessTransactionManager so there are no interactions with a database for Spring Batch meta-data. The only component that interacts with the database according to your configuration is the JdbcPagingItemReader (I don't know what is the type of your ReservationWriter) so it is not surprising to see a single database connection.

Spring Rest api, differentiating the response format based on parameter

Below is my RestController class

System.out.println("EMPLOYEES");
return this.getEmployee();
}

How can I solve this problem ?

Looks like you are using spring security filter in your application.
Can you post your web.xml?

You have to define in you web.xml
filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Fail to create bean in spring suddently

I have encountered a problem of failed to create bean in spring suddenly. The webapp is already deployed and has been running for several months. However, below error message comes suddenly. It can be resolved by restarting the webapp, but comes again without any hints. Does anyone have any idea of this case?
Tomcat 6 is being used to host the webapp.

Update:
Here's my xml with the <value> tag added which causes a different error message:
Invalid content was found starting with element 'util:constant'. No child element is expected at this point.
(Sidenote: for some reason my formatting controls have disappeared when posting in SO)

For enum's you can directly assign the values and Spring will take care of binding it to the correct enum:
<constructor-arg index="3" value="SECONDS">
Also, your original entry worked for me perfectly:
<bean id="threadPoolExecutor" class="java.util.concurrent.ThreadPoolExecutor">
<constructor-arg index="0" value="2"/>
<constructor-arg index="1" value="2"/>
<constructor-arg index="2" value="10"/>
<constructor-arg index="3"><util:constant static-field="java.util.concurrent.TimeUnit.SECONDS"/></constructor-arg>
<constructor-arg index="4" ref="arrayBlockingPool"/>
</bean>
