Description

git clone https://github.com/apache/olingo-odata2
cd olingo-odata2/odata2-jpa-processor/jpa-core
mvn install
...
Failed tests:   testBuild(org.apache.olingo.odata2.jpa.processor.core.jpql.JPQLJoinStatementBuilderTest): expected:<... 'abc' ORDER BY mat.[buyerId asc , mat.city de]sc> but was:<... 'abc' ORDER BY mat.[city desc , mat.buyerId a]sc>
...

With java 1.7 it works:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.7)
mvn install
...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS

It is likely a hashmap which should be replaced with LinkedHashMap.
