RFR(XS): 8132980: Improve stability of whitebox methods getCodeBlob and freeCodeBlob

[Stas Smirnov]

Hi,

changes looks good, one small remark, in one case when "addr == 0" you 
just make a return and in another case you THROW_MSG_NULL is there any 
specific reason for a different way of handling the same condition?
