    <p>for some cell in XLSX file rt.getFontAtIndex(i) part is just crashing and control is just exiting the function and even calling function. Out Swing windows is still open though. I have no clues why without any exception control is going out of the code.</p> <pre><code> public static String addLinkTagInRichTextForUnderscores(XSSFRichTextString rt) { System.out.print("Was here 1\n"); if(rt.length()==0 || rt == null) { return " "; } String outString = rt.toString(); //String finalString = ""; List&lt;Integer&gt; startIndexListOfUL = new ArrayList&lt;Integer&gt;(); boolean continuing = false; System.out.println(outString +" A "+ rt.length() +"\n\n"); for(int i=1;i&lt;rt.length();i++) { System.out.print("Was here at font "+ i); XSSFFont font = null; try{ //font = rt.getFontAtIndex(i); } catch(Error e){ e.fillInStackTrace(); } System.out.print("Was here too" + rt.getFontAtIndex(i)); if(font!= null) { if(XSSFFont.U_SINGLE == font.getUnderline()) { if(!continuing){ startIndexListOfUL.add(new Integer(i)); continuing = true; } }else{ continuing = false; } } else { //System.out.println("No font " + i); } } System.out.println(startIndexListOfUL); if(startIndexListOfUL.size()==0) { //finalString = outString; return " "; } else { int spacing = 0; for(int i = 0; i&lt;startIndexListOfUL.size(); i++) { outString = insertStringAt(outString,startIndexListOfUL.get(i) + spacing,"&lt;link&gt;"); spacing = spacing + 6; } } //just remove redundant &lt;link&gt; tags outString = outString.replaceAll("(&lt;link&gt;[\\s]?&lt;link&gt;)", "&lt;link&gt;"); //System.out.println("Final &gt;&gt;&gt;&gt; " + outString); return outString; } </code></pre>

    1. COWhy do you think that your Swing GUI would crash in this situation? It will only behave as you (your code) tell it to behave. How do you handle your Swing threading? How do you tell Swing to respond to crashes in the non-GUI thread?

    2. COIn fact, I see no threading code, no SwingWorker code, and in fact no Swing code at all in your post above, making it very hard to understand what in fact you might be doing, and you you're handling exceptions. Are you using a SwingWorker? If so, are you calling the SwingWorker's `get()` method? And if so, are you catching the exceptions it might throw? ....

    3. COWsing worker was calling one class function which intern was calling above mentioned class. Issue has been resolved. XSSFRichTextString has the bug.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
