Currently, the JDK7 build fails if it runs in non-English locale, say Japanese as follows (this is on Solaris with ja_JP.UTF-8 locale):

The reason of the problem is that the following line is in make/common/shared/Defs.gmk:

USER_RELEASE_SUFFIX := $(shell echo $(USER)_`date '+%d_%b_%Y_%H_%M' | tr "A-Z" "a-z"`)

The output of the 'date' command depends on the locale, which can lead to the build failure in non-English locales. In Japanese case, The month name is in Japanese, not like 'Apr'.
