Maven, test durumu çalışırken askıda kalıyor Eclipselink & hsqldb

Question

jps ve jstack kullanarak sorunlu bekleme iş parçacığına ulaşabilirim, ancak sorunu nasıl gidereceğimi veya neden kaynaklandığını bilmiyorum. Maven bağımlılıkları ve jstack sonucu ve tid=0x000000000022c000 ile bekleyen iş parçacığının altına bakın. Daha fazla analiz, seçilen sürümler için Eclipselink ve hsqldb arasında bir sorun gibi görünüyor. Bu sorunu, Eclipselink ve hsqldb'nin 2.0.1 ve 1.8.0.10 sürümleri için mükemmel çalıştığı için bu iki kitaplığı geliştirmenin sonucu olarak aldım.

Answer 1

Gerçekten bir hsqldb konuya benziyor. Solüsyon ne demekse bağlantı-url ;hsqldb.tx=mvcc için aşağıdaki eklemek için oldu from here takiben tarifi: Bu ben "güncelleme" hibernate.hbm2ddl.auto kullanarak yanı sıra bağlanmak için çiğ bağlantılarını kullanarak anlamına geliyordu benim için/

Answer 2

bellekte aynı HSQL'ye DB. İkisini ayrı HSQL db'lere ayırmak ve çalışmaya başladı. Şu anki teori: belki bir şey bir oturuma ya da işleme (özellikle bir tabloyu değiştiren) ve onu kapatmaya dayanmıyor mu? (Ne yazık ki benim durumumda yardımcı olmadı belirtilen mvcc düzeltme)

hsqldb sürüm 2.3.4, 4.0.1.Final

benim iz hazırda bekletme:
