This is fixed in DE511840 and the fix will be included into future release.
The workaround is to execute following with LANG=ja_JP.PCK:
-----
# /opt/CA/PAMSC/lbin/accommon_ini_japanese_uc_shift-jis.sh /opt/CA/PAMSCShared /opt/CA/PAMSCShared /opt/CA/PAMSC japanese_uc_shift-jis
# chmod 664 /opt/CA/PAMSCShared/data/japanese_uc_shift-jis/ini/accommon.ini
# cp -p /opt/CA/PAMSCShared/data/japanese_uc_shift-jis/ini/accommon.ini /opt/CA/PAMSCShared
# /opt/CA/PAMSC/bin/seini -s global.AC_Version 14.10.0.1265 /opt/CA/PAMSCShared/accommon.ini
# rm -rf /etc/accommon.ini
# ln -s /opt/CA/PAMSCShared/accommon.ini /etc

The global.AC_Version should be 14.10.0.1707 on CP3.
