The following tests have dependencies on PKCS11Test.java but do not compile it. Instead they are dependent on other tests in their respective directories to run first. The result is that these tests are failing intermittently, particularly in JPRT recently.

FAILED: sun/security/pkcs11/KeyStore/Basic.sh
FAILED: sun/security/pkcs11/KeyStore/ClientAuth.sh
FAILED: sun/security/pkcs11/KeyStore/Solaris.sh
FAILED: sun/security/pkcs11/Provider/ConfigQuotedString.sh
FAILED: sun/security/pkcs11/Provider/Login.sh

In all cases the tests fail with the error "Error: Could not find or load main class XXX" because the main class extends PKCS11Test.

For a quick fix then the shell tests can be changed to compile PKCS11Test.java, eg:

diff --git a/test/sun/security/pkcs11/Provider/Login.sh b/test/sun/security/pkcs11/Provider/Login.sh
--- a/test/sun/security/pkcs11/Provider/Login.sh
+++ b/test/sun/security/pkcs11/Provider/Login.sh

but it would be better to just get jtreg to compile the tests by adding a @build tag. Better still would be to eliminate the shell tests completely (at least in a few cases this is trivial to do).
