#1331 garbarge collection issue java 8 update 161 ?

[Alberto]

Hi, with squirrel 3.8.1 and windows 10 i have a problem with (i think) garbage collection.

After some times that squirrel is open the garbage indicator move fast and cpu goes to 30-40% .

For stopping cpu (and fan noise!) i must click on the basket icon to force garbage.

I think that issue is with the last java 8 update 161. Before that update was all ok.

Anyone have that issue?

My log is in attachments

I am on Windows 8.1 and noticed the same issue of increased CPU usage after the update from Java 131 to 161 (64 bit). I never force any garbage collection, but by just switching to a different database connection tab I already have open it reduces the constant CPU usage from 20% to 1%

I notice that for redecus CPU usage i must click on the taskbar or other element of the GUI!
I do a query and CPU increase, if i click on menù or the same table with result, cpu stop and return normally.
Very strange.

On my Windows 7 system I saw increased CPU usage with Java 8 161 (64 bit), too. It is quite possible that it results from this issue:

CPU is normally!

I have this same problem.
CPU goes to about 30% and the memory usage bar in Squirrel SQL (next to the garbage can) continuously increases and decreases in a repeating cycle. When I click the garbage can it will stop the memory usage bar from cycling and the cpu will return to normal. However, after a while it will start back up again.

Using:
Windows 7 Enterprise
SQuirreL SQL Client Version 3.8.1
Java: Version 8 Update 161
java.runtime.version: 1.8.0_161-b12
java.vm.version: 25.161-b12

As mentioned above this is a of Java Version 8 Update 161.
