Glenn Crilley commented on XALANJ-2168:
---------------------------------------
A fix to source module ElemCopyOf.java in the org.apache.xalan.templates
package. After line 186 add the following line:
xctxt.release(dtm, true);
Apply this fix appears to have corrected the memory leak. We will be
performing other tests to verify the fix and to ensure nothing else has been
broken.
update block of code is shown below:
while (DTM.NULL != (pos = nl.nextNode()))
{
DTM dtm = xctxt.getDTMManager().getDTM(pos);
short t = dtm.getNodeType(pos);
// If we just copy the whole document, a startDoc and endDoc get
// generated, so we need to only walk the child nodes.
if (t == DTM.DOCUMENT_NODE)
{
for (int child = dtm.getFirstChild(pos); child != DTM.NULL;
child = dtm.getNextSibling(child))
{
tw.traverse(child);
}
}
else if (t == DTM.ATTRIBUTE_NODE)
{
SerializerUtils.addAttribute(handler, pos);
}
else
{
tw.traverse(pos);
}
xctxt.release(dtm, true); // This is the code fix
}
}
