對於我們使用Seam構建的Web應用程序，有很多服務器測試用例。這些可以在多個系統上運行（Mac OS X和Linux）;通常，您可以克隆存儲庫並運行測試用例，而不會出現任何問題。交易同步註冊問題
但是，測試用例不能在我們團隊中一個人的筆記本電腦上運行。他在聯想筆記本電腦上使用Fedora Core。我們會遇到以下異常時，將應用程序部署到Seam使用的單元/集成測試嵌入式的JBoss：

測試環境使用HSQLDB 2.1.0。如前所述，測試用例可以在其他Linux機器上順利運行（也可以在Fedora Core上運行）。有誰知道，什麼可能會影響CMTTransaction，以便在這臺特定的機器上不允許事務同步註冊？
