Hello, We're using the Code Macro estension ( http://extensions.xwiki.org/xwiki/bin/view/Extension/Code+Macro ). We are using it like this: {{code language="java"}} our code {{/code}} And then this error appears: org.xwiki.rendering.macro.MacroExecutionException: Failed to highlight content at org.xwiki.rendering.internal.macro.code.CodeMacro.parseContent(CodeMacro.java:108) at org.xwiki.rendering.internal.macro.code.CodeMacro.parseContent(CodeMacro.java:48) at org.xwiki.rendering.macro.box.AbstractBoxMacro.execute(AbstractBoxMacro.java:146) at org.xwiki.rendering.macro.box.AbstractBoxMacro.execute(AbstractBoxMacro.java:51) at org.xwiki.rendering.internal.transformation.macro.MacroTransformation.transformOnce(MacroTransformation.java:184) at org.xwiki.rendering.internal.transformation.macro.MacroTransformation.transform(MacroTransformation.java:129) at org.xwiki.rendering.internal.transformation.DefaultTransformationManager.performTransformations(DefaultTransformationManager.java:72) at com.xpn.xwiki.doc.XWikiDocument.performSyntaxConversion(XWikiDocument.java:7605) at com.xpn.xwiki.doc.XWikiDocument.performSyntaxConversion(XWikiDocument.java:7554) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:836) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:785) at com.xpn.xwiki.doc.XWikiDocument.getRenderedContent(XWikiDocument.java:879) ...........

We thought that the code we added may be wrong, but if we just write {{code language="java"}}{{/code}} , we get the same error. Any clue of what's causing this error? Thanks in Advance Sergio Carrasco
