Hi, I'm using 1.5.1, yet. On mac osx 10.8.3. Recently I installed jdk-7u17-macosx-x64. After that sketchs won't run. I found a thread here telling to delete a folder inside javaVirtual folder. Done that, sketches are back working. But that made me think, can I use a 64 bits virtual machine? I'm full of memory(16gb), but Processing still only allows me to use 2000mb...

" can I use a 64 bits virtual machine?"
Apparently, that's what you do, no?

" Processing still only allows me to use 2000mb"
What limits you?

Well, that was a lazy question, sorry. Here goes the details. When i updated to jdk 7u-17-x64, whenever i tried to run any sketch, i got the message:

[0] "Error: This Java instance does not support a 32-bit JVM."

[1] "Please install the desired version."

Using startup command:

{command=command=java -d32 -Xrunjdwp:transport=dt_socket,address=127.0.0.1:8933,suspend=y -Xms64m -Xmx2000m -Xdock:name=_text00 -Djava.library.path=:/Applications/Processing.app/Contents/Resources/Java:/System/Library/PrivateFrameworks/JavaApplicationLauncher.framework/Resources:.:/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java -cp /var/folders/ry/ncychs9s2pd5cncqg93fx0zm0000gn/T/_text005206904213329528309temp:/Applications/Processing.app/Contents/Resources/Java/pde.jar:/Applications/Processing.app/Contents/Resources/Java/core.jar:/Applications/Processing.app/Contents/Resources/Java/ant.jar:/Applications/Processing.app/Contents/Resources/Java/ant-launcher.jar:/Applications/Processing.app/Contents/Resources/Java/antlr.jar:/Applications/Processing.app/Contents/Resources/Java/ecj.jar:/Applications/Processing.app/Contents/Resources/Java/jna.jar:/Applications/Processing.app/Contents/Resources/Java/quaqua.jar -ea processing.core.PApplet "--editor-location=640,275" --external --display=1 --sketch-path=/Users/vk/Documents/Processing/_text00 _text00 , quote=quote=", address=address=127.0.0.1:8933}

Then I found this thread suggesting to remove the folder /Library/Java/JavaVirtualMachines. That resolved the issue, and sketches are running again. But memory still limited to 2100mb. If I try any higher setting the sketch don't run, throwing:

com.sun.jdi.connect.VMStartException: VM initialization failed for: java -d32 -Xrunjdwp:transport=dt_socket,address=127.0.0.1:8260,suspend=y -Xms64m -Xmx2200m -Xdock:name=_text00 -Djava.library.path=:/Applications/Processing.app/Contents/Resources/Java:/System/Library/PrivateFrameworks/JavaApplicationLauncher.framework/Resources:.:/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java -cp /var/folders/ry/ncychs9s2pd5cncqg93fx0zm0000gn/T/_text00282090576309912186temp:/Applications/Processing.app/Contents/Resources/Java/pde.jar:/Applications/Processing.app/Contents/Resources/Java/core.jar:/Applications/Processing.app/Contents/Resources/Java/ant.jar:/Applications/Processing.app/Contents/Resources/Java/ant-launcher.jar:/Applications/Processing.app/Contents/Resources/Java/antlr.jar:/Applications/Processing.app/Contents/Resources/Java/ecj.jar:/Applications/Processing.app/Contents/Resources/Java/jna.jar:/Applications/Processing.app/Contents/Resources/Java/quaqua.jar -ea processing.core.PApplet --location=605,153 --external --display=1 --sketch-path=/Users/vk/Documents/Processing/_text00 _text00

Could not run the sketch (Target VM failed to initialize).

Make sure that you haven't set the maximum available memory too high.

For more information, read revisions.txt and Help ? Troubleshooting.

So this is the scenario. And my question is can I run in 64 bits, to have more memory allocated to the sketch? How?

I have seen this in wiki, but it is kind of laconic... i didn't understand...

Mmm, the -d32 option is the part that forces your Java to run in 32-bit mode, even with the 64-bit version.
I don't know how Processing is run on MacOS, but maybe you can find somewhere a file specifying these command line parameters. Starting with preferences.txt, for example.

v.k.

Well, thanks Philho, but i got no luck finding this command line. I have noticed that the IDE runs as 64bits, but the sketches don't... Any other idea?
