[Java] Mac: Eclipse: Java Heap Error --- adjustments in build.xml needed

Hi Tom,

 here is my high level of my scripts being run

in my setup script i am making calls to github which means checkout times
can vary within the terminal so I have thinktime next to the wait method
from sikuli.

here is an example of that:

                    s.type(null, gitCommand, 0);

                    thinktime(50000);

                    s.wait(Images.TERMINAL_GITCHECKOUTCOMPLETE_TEXT, 500);

                    thinktime(3000);

                    s.type(null, "cd " + absolutePathOfSinglesIphoneDir + "
\r", 0);

                    thinktime(2000);

                    s.type(null, "git submodule init \r", 0);

                    thinktime(2000);

                    s.wait(Images.TERMINAL_GITINITCOMPLETE_TEXT, 500);

                    thinktime(2000);

                    s.type(null, "git submodule update \r", 0);

                    thinktime(50000);

                    s.wait(Images.TERMINAL_GITUPDATECOMPLETE_TEXT, 500);

                    thinktime(2000);

                    s.type(null, "cd " + absolutePathOfSinglesIphoneDir + "
\r", 0);

Following the setup method I run some find method from Sikuli inconjunction
with another library called robot and run test like this:

@Test

public void testFemaleGenderPositiveEntry() throws Exception {

 String result = "";

 MobileUtils.thinktime(THINKTIME);

 s.find("imgs/EharmonyHeader.png");

 robot.mouseMove((s.getLastMatch().below().getX() + 235), (s

.getLastMatch().below().getY() + 120));

 MobileUtils.thinktime(THINKTIME);

 robot.mousePress(InputEvent.BUTTON1_MASK);

robot.mouseRelease(InputEvent.BUTTON1_MASK);

 MobileUtils.thinktime(THINKTIME);

 if (s.find("imgs/GenderFemaleEnabled.png") != null) {

result = "true";

}

 assertTrue(

"The gender selector should be set to Woman defined in a pink selection.",

result.contains("true"));

 } // end method

There are 20 more test almost like this one that continue to run before the
crash occurs. Something I should mention here I have not had this problem in
the past with your previous version of sikuli.

The images are 2-4k pngs, and I will have to get back to you on objects size
before garbage collection.

thanks,
JJacquet

OK worries are gone!

It turns out to be the build.xml

The maxmemory for the build xml in runAll targets was not set causing the test to blow up. However, the maxmemory enhancement in the build.xml was necessary due to java errors when using sikuli. I increased the .plist file and forkmode adjustments in the xml. The problem is now gone.

Turned out to not to be Sikuli bug - but information seems valuable

solved by user himself

the .plist file modification was not necessary to be clear. the issue for Jeremiah was that the target he was calling did not have the maxmemory="2048m" in his junit node of his target.....once he added that, he was good to go :) Remember to add maxmemory="2048m" wherever necessary in your targets to increase heap size in your ant build file. Obviously the number 2048 can get bigger if you want more memory allocated to your target.
