Description

With JDK 9-ea b111 there are a number of test failures.

Tests that use ClassLoaderTestSetup fail because the context class loader no longer is a URLClassLoader, which causes a ClassCastException in the class loader magic performed by the test setup:

java.lang.ClassCastException: jdk.internal.loader.ClassLoaders$AppClassLoader (in module: java.base) cannot be cast to java.net.URLClassLoader (in module: java.base)

	at org.apache.derbyTesting.junit.BaseTestSetup.run(BaseTestSetup.java:58)

CollationTest, CollationTest2, LocalizedAttributeScriptTest and LocalizedDisplayScriptTest have failures, for example:

junit.framework.AssertionFailedError: Column value mismatch @ column 'ID', row 1:
    Expected: >4<
    Found:    >6<

And the stack trace deletion patterns in the Sed class seem to be missing out on some stack frames now, causing failures like this one in dblook_test and dblook_test_territory:
