TBCFree: Could not create the Java Virtual Machine error (memory issues)

[osma.s...@helsinki.fi]

Hi!

I'm trying out TBC Free edition 4.4.0 under a 32 bit Windows 7 virtual machine with 1GB RAM. I've previously used TBC Standard 4.3.0 in this same VM so I know TBC works in this environment, which I use for testing Windows applications (I use Linux myself).

After unzipping the distribution package and trying to start TopBraid Composer, I get this error dialog:

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

A separate error dialog says:
Java was started but returned exit code=1
[...lots of debug output including the Java settings]

I traced this problem to memory issues. It seems that in 4.4.0 the Java memory settings have been increased. I took the working memory settings from 4.3.0 and changed these parameters in TopBraid Composer.ini:
-Xmx512M (was: 2048M)
-Xms256M (was: 640M)

After this change, I can at least start up TBC Free. However, it seems to change back the .ini file settings when I run it once, so it will not work another time.

Is this intended behavior, should I just add more RAM? Is the apparent hike in memory requirements documented somewhere?

Thanks,
Osma

Hi Osma. You will want at least 2G.

You will see two topbraid composer ini files. One will have an extension if orig. make the xmx change there as well. Then restart the application. This should resolve this for you. 

Thanks,

Mark

Thanks Mark!

It's OK, I can easily increase the memory for my VM. I'm just curious
because some of the users I need to support may have old machines with
low memory. At least now I know that I need to adjust the orig file as well.
