Description Jiri Skrivanek 2014-01-24 12:31:40 UTC
Because implementation of HashSet was changed in JDK8 SQL code completion now shows items in different order than with JDK7. That's why some tests fail because golden files differ. Possibly TreeSet should be used at some places instead of HashSet. To reproduce:

ant -f db.sql.editor test-unit -Dtest.includes=**/SelectCompletionQueryTest.class

To test HashSet behaviour simly use:

        System.out.println("java=" + System.getProperty("java.version"));
        Set<String> s = new HashSet<>();
        for (String item : s) {
            System.out.println("item=" + item);

Log: #240924 - Tests removed from stableBTD config until they are fixed.
Comment 2 matthias42 2015-02-15 13:11:16 UTC
I committed:

with that change the tests work on OpenJDK 7 + 8:

java version "1.7.0_75"
OpenJDK Runtime Environment (IcedTea 2.5.4) (7u75-2.5.4-1~utopic1)
OpenJDK 64-Bit Server VM (build 24.75-b04, mixed mode)

openjdk version "1.8.0-jdk8u40-b18"
OpenJDK Runtime Environment (build 1.8.0-jdk8u40-b18-20141217)
OpenJDK 64-Bit Server VM (build 25.40-b23, mixed mode)

As these are common parts of OracleJDK + OpenJDK this should validate the fix.

Jiri: Please check from your side - Thank you!
