No fields appear after username in Workflow configuration page

I got a mail about an issue after April 2010 CPU patches. Nothing was appearing after the user field in Workflow Configuration page in Oracle Applications Manager

Solution was given by Imran:

"NOTE: - Execute the steps given in 1082747.1 - defective share.zip After applying this patch"

The issue was related to the missing class files under $JAVA_TOP/oracle/bali/share/nls folder, after restoring them the issue was fixed.
