RFR: JDK-8142333: Build failure in debugInfoRec.cpp with SS12u4

[Erik Joelsson]

Hello,

The following new build failure has appeared in the hotspot build when 
using the proposed new compiler version on Solaris, SS12u4.

"/opt/jprt/jprtadm/erik/jdk9-dev/hotspot/src/share/vm/code/debugInfoRec.cpp", 
line 281: Error: static DIR_Chunk::compare(DIR_Chunk*const&, 
DIR_Chunk*const&) is not accessible from 
GrowableArray<DIR_Chunk*>::insert_sorted<&DIR_Chunk::compare>(DIR_Chunk*&).
"/opt/jprt/jprtadm/erik/jdk9-dev/hotspot/src/share/vm/code/debugInfoRec.cpp", 
line 281: Where: While instantiating 
"GrowableArray<DIR_Chunk*>::insert_sorted<&DIR_Chunk::compare>(DIR_Chunk*&)". 

"/opt/jprt/jprtadm/erik/jdk9-dev/hotspot/src/share/vm/code/debugInfoRec.cpp", 
line 281: Where: Instantiated from non-template code.

Tom Rodriguez provided a patch and I have verified that it solves the 
issue. Since this is blocking us upgrading compilers on Solaris, I am 
taking the liberty of posting it for review so we may get this resolved 
quickly.
