Doctor Jekyll and Mr. Hyde Question for ADF

Question

Hi all,
I have the following problem.
Below there are two codes that works fine but with these error.
The code in CASE 1 if the RowSet is more large it throws an OutOfMemoryException.
The code in CASE 2 work fine but it stop the resetting of
Application Module until i kill the session by killing the browser instance.
The code in CASE 2 (with -Djbo.debugoutput=console param) shows the following log:
(all ok) .....
06/01/18 09:31:15 [3189] ViewObjectImpl.mDefaultMaxRowsPerNode is 70
06/01/18 09:31:15 [3190] ViewObjectImpl.mDefaultMaxActiveNodes is 30
06/01/18 09:31:15 [3191] Default locking mode changed to: optimistic
06/01/18 09:31:15 [3192] Resetting AM=AppModule
now still in wait until i kill session.
After i kill session by killing the browser instance continue with the normal log
06/01/18 09:31:58 [3193] Application Module failover is enabled
06/01/18 09:31:58 [3194] Getting a connection for internal use...

06/01/18 09:31:58 [3197] <AM MomVer="0">

Can anyone help me to resolve this impasse?
Thanks

[in bold the difference code]
CASE 1:
OutputStreamWriter out_tmp = new OutputStreamWriter(new FileOutputStream(fileName, true));
int numTotRows = vo.getRowCount();
String[] attachFile = new String[numTotRows+1];
Row currRow = vo.getRowSet().first();
for (int rowIndex = 1; rowIndex <= numTotRows; rowIndex++) {
for (int attrIndex = 0; attrIndex < vo.getAttributeCount(); attrIndex++) {
if ((currRow.getAttribute(attrIndex) != null)) {
if (attachFile[rowIndex] == null) {
attachFile[rowIndex] = currRow.getAttribute(attrIndex).toString().trim() + "|";
} else {
attachFile[rowIndex] = attachFile[rowIndex] + currRow.getAttribute(attrIndex).toString().trim() + "|";
} // END - for (int attrIndex = 0; attrIndex < vo.getAttributeCount(); attrIndex++)
currRow = vo.getRowSet().next();
} // END - for (int rowIndex = 1; rowIndex <= numTotRows; rowIndex++)
for (int i = 0; i < attachFile.length; i++) {
out_tmp.write(attachFile);
out_tmp.flush();
out_tmp.close();
CASE 2:
OutputStreamWriter out_tmp = new OutputStreamWriter(new FileOutputStream(fileName, true));
int numTotRows = vo.getRowCount();
String[] attachFile = new String[] {""};
Row currRow = vo.getRowSet().first();
for (int rowIndex = 1; rowIndex <= numTotRows; rowIndex++) {
for (int attrIndex = 0; attrIndex < vo.getAttributeCount(); attrIndex++) {
if ((currRow.getAttribute(attrIndex) != null)) {
attachFile[0] = attachFile[0] + currRow.getAttribute(attrIndex).toString().trim() + "|";
} // END - for (int attrIndex = 0; attrIndex < vo.getAttributeCount(); attrIndex++)
[b]for (int i = 0; i < attachFile.length; i++) {
out_tmp.write(attachFile);
out_tmp.flush();
attachFile = new String[] {""};
currRow = vo.getRowSet().next();
} // END - for (int rowIndex = 1; rowIndex <= numTotRows; rowIndex++)
out_tmp.flush();
out_tmp.close();

Hi,
there is someone with an idea?
I'm very desperate!
Thanks
