Tested on XWiki 14.10.18 Standard HSQL Database Engine 2.7.1 with LibreOffice 7.5.8.2, Chrome 119

Results:

1. Importing the file with style filter selected worked very slow (as expected) but with no errors. The page can be accessed but it takes some seconds till it opens.
2. Importing the file with style filter deselected crashed the wiki - "java.lang.OutOfMemoryError: Java heap space" errors appeared in the wiki page and in the console. To resolve this issue the start_xwiki.bat file was edited and the "XWIKI_OPTS=-Xmx1024m" modified to
   • "XWIKI_OPTS=-Xmx2048m" - import worked very slow but with no errors, accessing the page works also very slow
   • "XWIKI_OPTS=-Xmx3072m" - importing and accessing the page works a few seconds faster with no errors
