Java.lang.OutOfMemoryError when running java concurrent program

Question

Hi,
i had written a java concurrent program to create the content items into Oracle Content Manager (OCM). Process the records from interface table and create the content items into OCM by calling the API IBC_CITEM_ADMIN_GRP.upsert_item().
I run the concurrent program with 2000 records in interface table, it's an one to one process, 563 records are processed and 563 content items are created successfully in OCM. After 563 records continuously throws the Exception
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.put_line('EX - bundle validation others--');
x_return_status := FND_API.G_RET_STS_ERROR;
FND_MESSAGE.Set_Name('IBC', 'A_BUNDLE_ERROR');
FND_MESSAGE.set_token('SITUATION', 'VALIDATION');
FND_MSG_PUB.ADD;
IF IBC_DEBUG_PVT.debug_enabled THEN
IBC_DEBUG_PVT.end_process(
IBC_DEBUG_PVT.make_parameter_list(
p_tag => 'OUTPUT',
p_parms => JTF_VARCHAR2_TABLE_4000(
'x_return_status', '*** EXCEPTION *** [' || SQLERRM || ']'
END IF;
in IBC_CITEM_ADMIN_GRP.validate_attribute_bundle() API.
Again running the concurrent program it process another 563 records. Can any one help me to fix this issue?
i figured out the exception. When debug the error, i got the actual error message like this
ORA-29532: Java call terminated by uncaught Java exception: java.lang.OutOfMemoryError
ORA-29532: Java call terminated by uncaught Java exception: java.lang.NullPointerException
ORA-29532: Java call terminated by uncaught Java exception: java.lang.ArrayIndexOutOfBoundsException: -2048 < 0
for this issue i increased the heap memory size up to 1024MB. Still i have the same issue. Can any one help to fix the issue?

ORA-29532: Java call terminated by uncaught Java
exception: java.lang.NullPointerException
ORA-29532: Java call terminated by uncaught Java
exception: java.lang.ArrayIndexOutOfBoundsException:
-2048 < 0Aren't the null pointer and arrayindexoutofbounds, the ones which you get when you are trying to read beyond your array? (example: when your loop tries to access the 563rd element in your array, since your array index starts from 0)?
May be if you can try to write out your elements in the array, you might see what it is croaking about.
Thanks,
