java.lang.OutOfMemoryError when loading sketch

Using Arduino IDE 1.x

Salut,

after staring the IDE, I get the following error when opening the third sketch:

This happens on three PCs, always when opening the third sketch, even if all you do is to open three sketches. I tried with arduino IDE 1.0.5 as well as 1.5.5rc2.
I have windows 7 enterprise 64bit or windows 7 home 64bit, jave is version 7U51
I searched the forum as well as the web but only found this error linked to autoformat

Any help is appreciated
Ciao, Mathias

Salut,

looks like I am the only one with this problem. Well, in case someone is interested in the fix anyway:
I replaced the call to javaw by the call to the installed JRE (7.51) and changed the heap parameters at startup to -Xms128m -Xmx1024m (was -Xms128m -Xmx128m)

Ciao, Mathias

Hi Mathias,

I'm not sure if I am running into a related prob, at least it sounds similar... (error message)
So, WHERE can I find the access to JRE settings? (W7U64)

Cheers,

Thx for your message,

and yes, you're correct: my issue is not a Java issue. It has been solved, it was a bootloader issue that played "hide and seek" with my windows. :wink:

Cheers
