Subject Re: [classlib][luni] String.toLowerCase/toUpperCase incorrect for supplementary characters (HARMONY-6649)
Date Fri, 24 Sep 2010 06:35:19 GMT
On loading junit.jar[2] i get initialization exception[3]. This
exception disappears if i revert the patch committed for
(HARMONY-6649) toUpper/toLowerCase.

Make sure your junit.jar contains the signature files[1]. (use the
junit.jar(version 3.8.2) bundled with eclipse).  So with HARMONY-6649
commit, I am not able to load the jar file if it's manifest contains
any signature related files. Any thought on this?
