Detailed Notes on java project help-XX:InitialHeapSize=6m In case you established this option to 0, then the Original size is ready given that the sum on the dimensions allocated with the previous technology plus the young era. The dimensions with the heap with the younger era may be set utilizing the -XX:NewSize possibility.
When current at run time, --illegal-accessibility= normally takes a key word parameter to specify a method of operation:
Identifies String objects reaching the specified age that happen to be deemed candidates for deduplication. An object's age is often a measure of how many times it's got survived rubbish assortment. This is typically generally known as tenuring. See the -XX:+PrintTenuringDistribution alternative.
