#1530 Memory leak

Version 4.7.1, JDK jdk-17.0.9+9, application run w/ option : -Xmx640m

There is a memory leakage, here's an example:

Open application
Open Mysql session ( session content row limit : 10000 )
Used memory: 88mb; force GC: 29mb
open table : 10000 rows / 27 columns
Used memory: 172mb : force GC: 39mb
execute: select of 440k rows
Used memory: 578mb; force GC: 512mb
Close result tab
force GC: 447mb
select 100k rows
Used memory: 553
close result tab
force GC: 534 mb
select 440k rows
java.lang.OutOfMemoryError: Java heap space

In some cases, when trying GK to 'reduce' the memory used, the application freezes, for example:

Used RAM 500MB - Execute 4 times "Select" which does not return the result (0 rows) in 4 Result Tabs ...
