I have a program thats real simple and will read through my xml file and print out some stuff. THe problem is the xml file is 2gb long and I cant run the program. Any options?

In that way it reflects the purpose of the old PermSize; flag. When MaxMetaspaceSize is set, the space can still run out of memory, which will cause a "java.lang.OutOfMemoryError: Metadata space".

A typical “standard Java” approach for detecting whether a String is null, is empty, or consists solely of white space is as shown in the next code listing.
