NullPointerException in javax.swing.text.GapContent.compare when inserting string

XMLWordPrintable

      FULL PRODUCT VERSION :
      $ java -version
      java version "1.7.0-ea"
      Java(TM) SE Runtime Environment (build 1.7.0-ea-b134)
      Java HotSpot(TM) 64-Bit Server VM (build 21.0-b04, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      $ uname -a
      Linux auto-centos5-64bit.funnelback.com 2.6.18-194.3.1.el5 #1 SMP Thu May 13 13:08:30 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux


      A DESCRIPTION OF THE PROBLEM :
      Using tika version 0.9 to convert a particular RTF file to text fails using the java 7 early access version on 64bit CentOS 5 (and I believe 64 bit Windows 2008) where it succeeds on 32 bit platforms and with java 6.


      The specific stack trace encountered, which seems to lead to javax.swing.text code is...

      $ java -jar tika-app-0.9.jar -t full.rtf
