java.util.EmptyStackException

[Hayri Bakici]

Hi, I have a problem regarding the parsing of css. I followed the instructions as they are described here. My code looks like the following:

CSSOMParser parser = new CSSOMParser();
InputSource source = new InputSource(new StringReader("p {color:#000000}"));
CSSStyleSheet sheet = parser.parseStyleSheet(source, null, null);

However the last line throws me the following exception:

java.util.EmptyStackException
at java.util.Stack.peek(Stack.java:85)
at java.util.Stack.pop(Stack.java:67)
at com.steadystate.css.parser.CSSOMParser$CSSOMHandler.endDocument(CSSOMParser.java:269)

at com.steadystate.css.parser.CSSOMParser.parseStyleSheet(CSSOMParser.java:144)

Thanks in advance

EDIT:

I found the problem, the parser was running on a different ClassLoader, therefore it was not able to work. This Question can be closed.

I'm getting the same issue. But not sure what was your ClassLoader issue. I don't see any ClassLoader here.

@Hayri: can you give more details?

Okay, I found out that CSSOMParser is not threadsafed. Fixed by using separate CSSOMParser instance each time.
