[PATCH RFC 0/5] fix build errors with gcc6

[Erik Joelsson]

Hello Guido,

Looking at your patches, none of them seem to actually be build system 
changes, but rather code changes in various parts of the product. I 
believe patch 1 and 5 should go to core-libs-dev and the rest to 
hotspot-dev. For number 5, assuming the component team is ok with 
disabling -Werror, then since it's a makefile change, it's also good 
practice to include build-dev.
