However, it ran long enough to cause enough concern to check the Java console and the following portion of the stack trace was observed:</p><p><code>Exception in thread "Thread-10" java.lang.OutOfMemoryError: Java heap space<br> at java.util.Arrays.copyOf(Unknown Source)<br> at java.util.Arrays.copyOf(Unknown Source)<br> at java.util.ArrayList.ensureCapacity(Unknown Source)<br> at java.util.ArrayList.add(Unknown Source)<br> at org.apache.poi.hssf.record.RecordFactory.createRecords(RecordFactory.java:400)<br> at org.apache.poi.hssf.usermodel.HSSFWorkbook.&lt;init&gt;(HSSFWorkbook.java:276)<br> at org.apache.poi.hssf.usermodel.HSSFWorkbook.&lt;init&gt;(HSSFWorkbook.java:201)<br> at org.apache.poi.hssf.usermodel.HSSFWorkbook.&lt;init&gt;(HSSFWorkbook.java:317)<br></code></p><p>Will retry with smaller files etc.</p><p>Keep up the good work</p><p>eagertask</p>eagertaskSat, 28 Mar 2009 21:06:43 -0000
