 Hi, I am using ipopt in java and I have a few questions.

 1) anyone could please provide me with a dll and a jar for java 64bit?
 Right now my project works only with the version for java 32 bit.

 2) my problem is rather big, 2-3,000 variables, a few equality
 constraints, and 2-3,000 inequality constraints.
 For up to 1,000 variables there is no problem, but when this number grows
 to 1,200 I get the following error:

 Is there a way to control memory allocation from the java interface?

 Thank you,
 Regards
