Using an un-initialized variable in a business process can result in diverse exceptions.
All variables in a business process have the value null when a process is started, the variables are not pre-initialized. Using an un-initialized variable inside a Java snippet or Java expression leads to a NullPointerException.
The variable must be initialized before it is used. This can be done by an assign activity, for example, the variable needs to occur on the to-spec of an assign, or the variable can be initialized inside a Java snippet.
