--- Comment #3 from Mark Wielaard <mark at gcc dot gnu.org> 2012-12-21 09:42:28 UTC --- The crash should of course not happen, but since jdom now depends on jaxen just including the jaxen.jar on the classpath seems to work around the issue: ./jc1 jdom.jar fhash-synchronization -fno-use-divide-subroutine -fuse-boehm-gc -fnon-call-exceptions -fkeep-inline-functions -quiet -g -O -o /tmp/jdom.s -fbootclasspath=/home/mark/install/share/java/libgcj-4.8.0.jar -fclasspath=jaxen.jar
