I have been trying to troubleshoot a java heap error for a good while, and I
have researched the error messages on this site without luck. I have a
6000+ page document with numerous tables - the largest tables being at the
front of the document, where they run fine. In dividing the document, I
find that it gets to slightly over 3000 pages before it dies. Because the
tables are simple two-column tables, I tried setting them up as lists in
list-blocks, but I still get a similar error. Following are the errors from
both the table and list versions:

Pertinent data: I'm using FOP 0.95 (started with 0.94 and had similar
errors) and jdk1.6.0_03. I've stripped out pretty much all attributes from
the fo: elements, but here's an example of a list:
<fo:list-block provisional-distance-between-starts="12pt"
provisional-label-separation="5pt" margin-left="36pt" start-indent="10pt">
<fo:list-item provisional-distance-between-starts="12pt"
provisional-label-separation="5pt" margin-left="36pt" start-indent="10pt">
<fo:list-item-label end-indent="label-end()">
<fo:block font-size="14pt">
<fo:inline>•</fo:inline>
</fo:block>
</fo:list-item-label>
<fo:list-item-body start-indent="body-start()">
<fo:block space-after="0pt"><fo:inline font-weight="bold">TEXT:
</fo:inline> and some more text. </fo:block>
</fo:list-item-body>
</fo:list-item>
<fo:list-item provisional-distance-between-starts="12pt"
provisional-label-separation="5pt" margin-left="36pt" start-indent="10pt">
<fo:list-item-label end-indent="label-end()">
<fo:block font-size="14pt">
<fo:inline>•</fo:inline>
</fo:block>
</fo:list-item-label>
<fo:list-item-body start-indent="body-start()">
<fo:block space-after="0pt">
<fo:inline font-weight="bold">TEXT: </fo:inline> More Text.
</fo:block>
</fo:list-item-body>
</fo:list-item>
</fo:list-block>
Any help would be most appreciated. Please let me know if additional
information would be helpful.
Regards,
David Kelly
