Wang, Gang commented on MNEMONIC-460:
-------------------------------------

Helper and verification code has been added to project, Run the following command got the result as below

 
{code:java}
$mvn exec:exec -Phelloworld -pl mnemonic-examples
{code}
{noformat}
Hello World!
The address of this durable string object: 0x00000000ED9439B4
The hash code of this durable string object: 0xC63CB61D
A string returned from the durable buffer: hello
The original string with the content of this durable buffer changed: hello
A new string returned from the same durable buffer: world
The address of the content of this durable buffer: 0x00007F1128008008
The base address of this memory space: 0x00007F1127FFF000
{noformat}
The result shows the String has been copied when it returns from a durable buffer and the durable buffer do in place updates.
