[8u] RFR 8151834: Test SmallPrimeExponentP.java times out intermittently

[Martin Balao]

Hi,

I'd like to request a review for the 8u backport of 8151834 [1]. This
backport would bring parity with Oracle's JDK. Risk is minimal as only a
test is affected.

Webrev.00:

 *
http://cr.openjdk.java.net/~mbalao/webrevs/8151834/8151834.webrev.jdk8u.jdk.00/

Main line patch does not apply cleanly because:

 * test/sun/security/mscapi/SmallPrimeExponentP.java
  * 3rd hook
   * 8u does not have "@key intermittent" line added by 8151835 [2] [3]
    * backporting 8151835 is not necessary because "@key intermittent"
will be removed by 8151834 (it was added to make clear that the test was
intermittently failing, and that's what's being fixed)
   * "@modules java.base/sun.security.x509" and
"java.base/sun.security.tools.keytool" lines were not available in 8u
because the test was not modules-aware. It won't be modules-aware
anyways but these lines (which will be added by 8151834) are harmless.

Testing:

 * test/sun/security/mscapi/SmallPrimeExponentP.java
  * Passed (tested on Windows)

Thanks,
Martin.-
