Bug ID: 58552
Summary: NPE at XWPFStyles.getUsedStyleList()
Product: POI
Version: 3.11-FINAL
Hardware: PC
Status: NEW
Severity: critical
Priority: P2
Component: XWPF
Assignee: [email protected]
Reporter: [email protected]
I tried to find used styles of style, which have 'next style', but has no 'link
style', using XWPFStyles.getUsedStyleList(XWPFStyle) method and got NPE at 174
line.
https://github.com/apache/poi/blob/REL_3_11_BRANCH/src/ooxml/java/org/apache/poi/xwpf/usermodel/XWPFStyles.java#L191
This part of code looks really suspicious:
String nextStyleID = style.getNextStyleID();
XWPFStyle nextStyle = getStyle(nextStyleID);
if((nextStyle!=null)&&(!usedStyleList.contains(nextStyle))){
usedStyleList.add(linkStyle);
getUsedStyleList(linkStyle, usedStyleList);
}
Probably this is a bug, and author mentioned that:
usedStyleList.add(nextStyle);
getUsedStyleList(nextStyle, usedStyleList);
So, trunk version of this class contains same part of code too.
