LIU WEN updated LOG4J2-2389:
----------------------------
Description:
* fix the CacheEntry map in ThrowableProxy#toExtendedStackTrace to be put and
gotten with same key
* stackTraceElement.toString() returns a string representation of this stack
trace element, just as MyClass.mash(MyClass.java)
* stackTraceElement.getClassName() returns the fully qualified name of the
Class, just as org.apache.logging.log4j.MyClass
{code:java}
final String className = stackTraceElement.getClassName();
……
final CacheEntry cacheEntry = map.get(className);
if (cacheEntry != null) {
final CacheEntry entry = cacheEntry;
extClassInfo = entry.element;
if (entry.loader != null) {
lastLoader = entry.loader;
}
} else {
final CacheEntry entry = this.toCacheEntry(stackTraceElement,
this.loadClass(lastLoader, className), false);
extClassInfo = entry.element;
map.put(stackTraceElement.toString(), entry);
if (entry.loader != null) {
lastLoader = entry.loader;
}
}
{code}
