The Mbean's name contain spaces leads to a bug

[skiof007]

example:
error:
$>bean -d java.lang java.lang:name=Perm Gen
#IllegalArgumentException: Bean name java.lang:name=Perm isn't valid
$>bean java.lang:name=Perm Gen,type=MemoryPool
#IllegalArgumentException: Please specify domain using either -d option or domain command

normal:
$>bean java.lang:name=CodeCacheManager,type=MemoryManager
#bean is set to java.lang:name=CodeCacheManager,type=MemoryManager

I have find at random what correct syntax with two backslashes.
For example: bean -d java.lang java.lang:name=Perm\\ Gen
