Optimized dexer errors

Hello,

I recently upgraded to 2.52 and since then when I compile something I get this (error) in the compile log/window:

Convert byte code - optimized dex.
Optimized dexer failed. Switching to Standard dexer.


Is this something to worry about?

it seems like it yes, and it's stuck on it for a while when it happens.

strange thing I noticed just now...

I opened the task manager and saw that java.exe was eating up all CPU power,
this was not constant but happened every xx seconds.

When I closed the 2 B4A sessions that behaviour went away.

I reopened B4A again and the compiling was a lot faster than last night and no dexer errors now.

Seems something got stuck here

one for each project that's open, sounds logical not?

there are also 3 adb.exe's running instead of 1, 2 use 24Kb (912Kb VM) and one 680Kb (2252Kb VM)

Edit: just double checked

there's 2 B4A.exe & 2 java.exe , javac.exe starts when compiling

not at the moment, it just took 20 seconds for that signing at my last compile.
All other passes are between 0.02 & 2.89 seconds

ok, there is an issue.

I went watching television for about 5 hours, when I got back the fan of this laptop was doing some heavy work.

When I opened task manager it was again a java.exe that was peaking.

Not sure if it was opened by B4A so I took a deeper look at the problem.

In the attachment you can see that B4A for some reason calls java.exe,
this happends every half a minute or so but since there are 2 code/ide sessions this happends twice in a minute so it's like 50 seconds 100% cpu and 10 seconds 0% cpu. then the cycle starts again.

I didn't touch the B4A since I returned, took the screenshot and posted this reply.
So it's doing stuff in the background without a usefull reason.

This is the optimized dexer. Though it usually doesn't take a lot of resources.

You can try one of these options:
- Disable it by setting MaxRamForDex to 0
- Increase MaxRamForDex to a higher value. If your project if quite big then it is better to use more memory.

This value is set in the INI file:
C:\Users\<user name>\AppData\Roaming\Anywhere Software\Basic4android

Make sure to close the IDE before you edit it.

I have to admit that this is an old laptop (1.6GHz & 1Gb RAM) but I'm unemployed and in the middle of a job search so I better wait for a new machine my employer will give me than to invest myself ;)

So on you 3GHz machine you probably don't notice it at all.

And why is that dexer being called every half minute when nothing has changed in the source?

using 0 was not smart apparently.

now I can't compile anymore.

Error: Could not create the Java Virtual Machine
Error: A fatal exeption has occured. Program will exit.
Invalid maximum heap size: -Xmx0m

64 fails
128 works but still deadslow at compiling

I have the impression that it was a lot faster in previous builds
