There is only last heap dump left ... reassigning to diff

Comment 3 Ondrej Vrabec 2014-07-03 07:18:45 UTC

almost 2 million instances of org.netbeans.lib.lexer.token.DefaultToken	related to an sql file of 7MB size. Possibly there is a memory leak in loading such a file.

Comment 4 matthias42 2016-08-26 15:46:46 UTC

I now looked through this multiple times. The sql lexer looks sane and does not keep excessive data around. The count of 2 million tokens for a 7MB file also looks reasonable.

As users are clearly warned about opening files > 1MB I'll close this here.
