I'm running into build failures while trying to build hotspot (only - not the JDK). It looks like the first of these is due to a change introduced in 2558:81d815b05abb while the second has been around forever.

hotspot/src/share/vm/oops/constantPoolOop.cpp:272:40: error: converting 'false' to pointer type 'methodOop' [-Werror=conversion-null] hotspot/src/share/vm/opto/loopnode.cpp:896:50: error: converting 'false' to pointer type 'Node*' [-Werror=conversion-null]

These were both fixed 6 months ago as bug 7140882:

http://hg.openjdk.java.net/hsx/hotspot-rt/hotspot/rev/f457154eee8b

The fix went into jdk8 and jdk7u4.

What version of hotspot sources do you have?

The cause for both of these is a conversion from bool to a pointer type conversion warning being treated as an error; that gcc (Debian 4.7.1-2) 4.7.1 doesn't seem to like.

Attached patch fixes this.

FYI the mailing lists tend to strip attachments.

Thanks, -Kaushik

PS: FWIW, here's the command I'm using to build: make LANG=C ARCHDATAMODEL=64 DISABLEHOTSPOTOSVERSIONCHECK=ok ALTBOOTDIR=/usr/lib/jvm/java-1.6.0-openjdk-amd64 jvmg
