JDK-8198484 - URLClassPath should use an ArrayDeque instead of a Stack

JDK-8198803 - URLClassLoader does not specify behavior when URL array contains null
Description
Currently a URLClassLoader instance will be successfully constructed if the URL array contains a null element but a NullPointerException will subsequently occur, e.g., in findClass() if the URLClassLoader is actually used.
Comments
This issue was fixed as a side-effect of the change in JDK-8198484. Though the specs for the methods still need to be updated - see JDK-8198803.

This issue is NOT a duplicate of JDK-7179567. JDK-7179567 and the related JDK-6445180 dealt with a null URL array, not with null elements within that array! There are test cases in the test pushed by JDK-6445180 that are commented out until this bug is fixed.

I cannot check this with JCK8 b36 in packet mode due to JCK-7301913 that fixed in b37 only. I checked this manually as it described in Chris's comments (comment - 2013-12-02 17:57) I used same command for b35 and b36 but different test location and different classpath. resuts below: JCK8 b35: jdk1.8.0/bin/java -cp /export/local/aurora/CommonData/jck_runtime_8/classes/ javasoft.sqe.tests.api.java.net.URLClassLoader.Ctor3Tests -TestCaseID ALL -TestURL file:////export/local/aurora/CommonData/jck_runtime_8/tests/api/java_net/URLClassLoader/index.html#Ctor3 Ctor3T101: Passed.

Sergei: We both appear to be using jdk8_b118, so there is either something environmental, or a difference in the JCK's we are running. I am running the tests from JCK b36.

Based on the test results above I see no issue. Can the submitter please confirm if there is still any issue.
