There were some recent changes to make/linux/makefiles/launcher.make,
so my patch no longer applies. Here is an updated patch.
I've verified that the patch is still needed (on Fedora 14 with
SELinux enabled), and that it is "complete", in the sense that
top-level make clean && make completes successfully.

Need reviewer: Misc fixes related to binary file checks
This started out as fixing a rebase bug but we also needed to verify
that our libraries were
built properly, so the binary_file_verification define was created to
do this.
The checks are not nailed down yet, but I need to get the calls to
the
binary_file_verification
define in place first.
Initially the plan was to do this check when the j2sdk-image was
created, but it seemed to make
sense to verify the binaries where they are created and as they get
imported in so we can catch
problem binaries as soon as possible.
6413588: Add 'ldd -r' and 'dump -Lv' checks to all .so files
delivered
in the JDK
6975326: Problem in install/make/rebase/Makefile, grep on empty
pattern
7000995: Add check in makefiles to verify that msvcp100.dll is NOT
used
http://cr.openjdk.java.net/~ohair/openjdk7/jdk7-build-binary_file_verification/webrev/
On Windows we currently want to make sure the DLL can have a Dynamic
base, and that it
is NX compatible (DEP).
On Solaris and Linux, there is mostly just runs of ldd, nm, and dump/
readobj, the specific
things we want to check for may take a little more time to nail down.
This binary_file_verification also provides some details in the build
log with regards
to the library dependencies, which may be of use someday in tracking
down dependency issues.

are both mainstream.
Hopefully, the usual Java backwards compatibility will be maintained,
so mostly it won't matter. However, the packages may be installed
side-by-side, with a symlink for the global default. Like this
example
from Fedora 13:
/usr/bin/java -->
/etc/alternatives/java -->
/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/bin/java
I can't yet comment on whether distros will choose to allow multiple
JDKs, though: just that there is no strong technical reason that
forbids it.
