unsafe.copyMemory call error

[shavy]

I have a project running with JDK1.6 and msgpack v0.6.0,when I try to update to msgpack v0.7,it gaves me errors like:

The method copyMemory(long, long, long) in the type Unsafe is not applicable for the arguments (byte[], int, Object, long, int) MessageBuffer.java

I google it and found it may cause by the copyMemory function with 5 params is available on JDK 1.7 only(not sure) .If so,how can I manage this problem without update my JDK to 1.7? thx for helping!

@xerial could you take a look?

@shavy As you mentioned, copyMemory of 5 args is not found in jdk6.
http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b27/sun/misc/Unsafe.java#Unsafe.copyMemory%28long%2Clong%2Clong%29

Ideally, we recommend to use JDK 7 or higher since JVM6 is no longer maintained, but I will seek a workaround.

Thanks for reporting.

Thanks for the workaround ,cause sometims the old project is too difficult to update a new JVM version
