-----------------------------------------
Summary: Many tests fail on JDK 8 because of missing collators
Key: DERBY-5958
URL: https://issues.apache.org/jira/browse/DERBY-5958
Project: Derby
Issue Type: Bug
Components: Test
Affects Versions: 10.10.0.0
Reporter: Knut Anders Hatlen
Many of the regression tests fail on JDK 8 after
http://bugs.sun.com/view_bug.do?bug_id=7171324 trimmed down the list of locales
returned by Collator.getAvailableLocales(). Many test cases assume that certain
locales are always available, even though the specification for
Collator.getAvailableLocales() only guarantees that Locale.US is available. We
should add guards to the collation-dependent test cases to prevent them from
running when the required locale is not available in the test environment.
The most common source of the failures in my environment is the lack of
collator support for the 'en' locale, with stack traces like this:
Caused by: ERROR XBM04: Collator support not available from the JVM for the
database's locale 'en'.

Those should be easy enough to fix by making the tests use 'en_US' for
territory, since support for that locale is required by the Java specification.
There are also other problems, like CollationTest2.suite(), which checks for
the availability for the "no" locale, and if it is available, it runs the test
with territory=no_NO. This does not work in an environment where the "no"
locale is supported and the "no_NO" locale isn't. We should change the
availability check and the actual database territory to match.
Another instance can be seen in tools/dblook_test_territory.java, which fails
if a collator for the nl_NL locale isn't available. Since this test runs in the
old test harness, which is less flexible when it comes to excluding tests based
on the environment, it might be best to convert it to JUnit first.
