Symptoms

Creating a WLDF module to detect OutOfMemoryError string in the server log file does not send the email notification.

The OOME generates the following line in the server log file:

<Error> <HTTP> <BEA-101017> <[ServletContext@xxx[app:ApplicationName module:ModuleName path:null spec-version:x.x]] Root cause of ServletException.
java.lang.OutOfMemoryError: Java heap space
>

Using the following policies, an email notification is successfully received:

log.logMessage.contains("ServletContext")
log.logMessage.contains("OOMTestEAR")
log.logMessage.contains("module ")
log.logMessage.contains("ServletException")

But with one of these policies, no notification is triggered:

log.logMessage.contains("java.lang")
log.logMessage.contains("OutOfMemoryError")
log.logMessage.contains("Java heap space")
