> Key: OWB-1388
> URL: https://issues.apache.org/jira/browse/OWB-1388
> Project: OpenWebBeans
> Issue Type: Bug

> *Problem*: Repeated instantiation of
> [ViolationMessageBuilder.java|https://github.com/apache/openwebbeans/blob/master/webbeans-impl/src/main/java/org/apache/webbeans/exception/helper/ViolationMessageBuilder.java]
> causes thread to block at java.util.Hashtable.
> Class :
> [https://github.com/apache/openwebbeans/blob/master/webbeans-impl/src/main/java/org/apache/webbeans/exception/helper/ViolationMessageBuilder.java]
> Current field :
> _private_ _final String lineSeparator =
> System.getProperty("line.separator");_
> _Currently it is getting instantiated every time
> *{color:#FF0000}ViolationMessageBuilder{color}* is instantiated by the code._
>
> *_Fix :_*
> Change it to static variable :
> _private {color:#FF0000}static{color} final String lineSeparator =
> System.getProperty("line.separator");_
> This will prevent java.util.HashTable
> (_System.getProperty("line.separator")_ being called every time
> {color:#FF0000}ViolationMessageBuilder{color} instantiated.
