PicketLink：'錯誤：無效字節序列編碼「UTF8」：設置密碼時爲0x00'

Question

我有一個Java EE應用程序配置爲使用PicketLink作爲其安全框架。該應用程序在JBoss EAP 7（或Wildfly 10）上運行，並使用PostgreSQL 9.4作爲其後端數據存儲。我初始化PicketLink IDM框架使用PBKDF2密碼編碼就像這樣：

builder.named("MyApp").stores().jpa() 
     .setCredentialHandlerProperty(PasswordCredentialHandler.PASSWORD_ENCODER, 
       new PBKDF2PasswordEncoder("salty".getBytes(), 10000, 128)) 
     .addContextInitializer(new PicketLinkContextInitializer(this.entityManager)); 

利用這種配置，但是，我定期試圖設置密碼時出現以下情況例外：

我說定期，因爲錯誤似乎並不是每一次都會發生。我可以設置少量的密碼（< 5），沒有任何問題。但是，如果我嘗試批量創建用戶帳戶，則每次都會發生錯誤。無論我創建多少個帳戶，我也偶爾會看到它偶爾出現。

任何想法爲什麼會發生此錯誤或我如何糾正它？

您試圖在字段數據類型的表列中存儲一個零字節，這在PostgreSQL中是不允許的。

使用PostgreSQL數據類型bytea代替它可以用來存儲任意的二進制數據。
