Inconsistent Javadoc comment and code for execute(TransformerImpl) in
org.apache.xalan.templates.ElemFallback
-------------------------------------------------------------------------------------------------------------
Key: XALANJ-2556
URL: https://issues.apache.org/jira/browse/XALANJ-2556
Project: XalanJ2
Issue Type: Bug
Security Level: No security risk; visible to anyone (Ordinary problems in
Xalan projects. Anybody can view the issue.)
Affects Versions: 2.7, 2.7.1
Environment: Platform Independent
Reporter: SHIN HWEI TAN
The Javadoc comment below states that the parameter transformer is a "non-null
reference to the the current transform-time state.":
/**
...
* @param transformer non-null reference to the the current transform-time
state.
...
*/
public void execute(TransformerImpl transformer) throws TransformerException
However, the method does not check the parameter for "null". It executes
normally without throwing any exception when called with a null transformer.
Suggested Fixes:
1. Add parameter check for "null"
or
2. Remove "non-null" from @param.
