I installed the Linux JREs for 6u10 b28, (using java -jar jre......jar) and was surprised to discover none of the programs (like "bin/java") were executable. I checked earlier 6u10 builds, and they have the same problem. I suspect the jdk7 builds also have this problem.
This seems like a P1 deployment bug. Hasn't anyone ever run sanity checks on JREs installed this way? Martin
