#1904 closed enhancement (fixed)

Display more memory usage details

Description

The "About" dialog display some information about used and available memory. While this can be useful, the most common memory issue is a "PermGen Space" out of memory error. This memory is a special section of the available memory and typically is less than 100 MB (I have seen number such as 64 and 82 MB).

Using ManagementFactory to retreive MemoryPoolMXBean instances can give us more detailed information about the memory. See https://docs.oracle.com/javase/7/docs/api/java/lang/management/ManagementFactory.html
