File Name : org.apache.catalina.core.StandardWrapper.java
CVS Revision : 1.44
Function Name : public Servlet allocate() throws ServletException
Line No's : 677 - 705
Explanation:
The allocate() function checks on singleThreadModel varibale within the
scope of if(!singleThreadModel), which is not needed.
The snippet is attached herewith. The nested "if(!singleThreadModel)" is
redundant as it lies in the scope if external if
and shall get executed only when the Servlet is not STM.
Starts at Line No - 677
if (!singleThreadModel) {
// Load and initialize our instance if necessary
if (instance == null) {
synchronized (this) {
if (instance == null) {
try {
if (log.isDebugEnabled())
log.debug("Allocating non-STM instance");
instance = loadServlet();
} catch (ServletException e) {
throw e;
} catch (Throwable e) {
throw new ServletException
(sm.getString("standardWrapper.allocate"),
e);
}
}
}
}
// This check is redundant as the condition is already checked
above
if (!singleThreadModel) {
if (log.isTraceEnabled())
log.trace(" Returning non-STM instance");
countAllocated++;
return (instance);
}
}
