jsp compile errors during patch 19486870

We apply patch 19486870 per recommendations in Doc 389422.1
That patch runs the jsp compile command $ perl -x /ap04/app/onetest/apps/apps_st/appl/fnd/12.0.0/patch/115/bin/ojspCompile.pl --compile --quiet

There are 4 compilation errors as shown below.

After the patch I tried to compile the jsp's again and they would not compile. This has happened in multiple R12 evironments.
