VisualVM Reading, - "Char[]"

Discussion in 'Performance Tweaking' started by notyetrated, Jan 7, 2013.

  1. Can anyone explain to me what "char[]" and "java.lang.String" are in my VisualVM heap dump? They are combined, consuming 80% of the "instances" on my server...

    I string is a collection of chars, eg "hello", and a char[] is also a collection of chars, ie what makes a String. There is a fair chance a plugin might be making a lot.
  3. Something such as hawkeye, which is currently logging all block place/destroy/chat/logins/commands/weather/humidity/celestial alignment..... etc...etc...
