Android DocxtoHTMl NOT working for Android 2.3.6

[manishiitk]

AndroidDocxHtml is NOT working on android 2.3.3 although it is working fine on above versions.

when trying on 2.3.3 it is throwing exceptions as
java.lang.ExceptionInInitializerError

at org.docx4j.openpackaging.contenttype.ContentTypeManager.parseContentTypesFile(ContentTypeManager.java:651)
at org.docx4j.openpackaging.io.LoadFromZipNG.process(LoadFromZipNG.java:206)
at org.docx4j.openpackaging.io.LoadFromZipNG.get(LoadFromZipNG.java:193)

i tried
WordprocessingMLPackage wordMLPackage = (WordprocessingMLPackage)loader.get(is);
also
WordprocessingMLPackage wordMLPackage = (WordprocessingMLPackage)OpcPackage.load(is,Filetype.ZippedPackage,null);

but getting same error with both ...
any suggestions ?
