How much memory can I allocate to JAVA_memory?

[emir]

I have 16 GB of RAM but max Owlready doesn't allow me to allocate more than 1.5 GB.
"Could not reserve enough space for 1710080KB object heap"

Why is it? Is there a way to increase that?

Replying to my own post.

Use the 64-bit version of java.
The 32-bit version won't allow you to increase JVM memory above ~ 1.7 GB.
