--- Comment #4 from Andreas <a.nieme...@euroimmun.de> ---
I tried a bit more debugging and think I found it.
Inspecting the NullLogger object, which is returned in the DocumentHelper
private static POILogger logger =
POILogFactory.getLogger(DocumentHelper.class);
there is a missing @Override annotation for the method public void log(int
level, Object obj1, final Throwable exception):
/**
* Log a message
*
* @param level One of DEBUG, INFO, WARN, ERROR, FATAL
* @param obj1 The object to log.
*/
@Override
public void log(final int level, final Object obj1)
{
// do nothing
}
/**
* Log a message
*
* @param level One of DEBUG, INFO, WARN, ERROR, FATAL
* @param obj1 The object to log. This is converted to a string.
* @param exception An exception to be logged
*/
public void log(int level, Object obj1, final Throwable exception) {
// do nothing
}
For probably that reason, the abstract method from the POILogger is called and
the exception reflecting it:
Caused by: java.lang.IllegalAccessError: tried to access method
org.apache.poi.util.POILogger.log(ILjava/lang/Object;Ljava/lang/Throwable;)V
from class org.apache.poi.util.DocumentHelper
at
org.apache.poi.util.DocumentHelper.trySetXercesSecurityManager(DocumentHelper.java:84)
at org.apache.poi.util.DocumentHelper.<clinit>(DocumentHelper.java:57)
Try using it with a call before the return should prove it (where t can be null
for testing purpose):
logger.log(POILogger.WARN, "SAX Security Manager - test logger", t);
BTW the older 3.12 version of the NullLogger class has the annotation above the
method.
Can you confirm?
Kind regards,
Andreas
