[Bug java/20116] New: gcj-dbtool merging seems to lose mappings

["overholt at redhat dot com" <gcc-bugzilla at gcc dot gnu dot org>]

For all of the Eclipse sub-RPMs, I'm trying to create mapping databases for
their jars and then merge each one with into the main eclipse.db.  Here is a
snippet of the problem I'm having (seemingly truncated databases after a merge):

[...]
gcj-dbtool4 -l /usr/lib/eclipse/eclipse.db | head -n 2

Size: 12374
gcj-dbtool4 -n /tmp/eclipse-ecj.db 80000
gcj-dbtool4 -a /tmp/eclipse-ecj.db \
/usr/share/eclipse/plugins/org.eclipse.jdt.core_3.1.0/jdtcore.jar \
/usr/lib/eclipse/plugins/org.eclipse.jdt.core_3.1.0/jdtcore.jar.so
gcj-dbtool4 -a /tmp/eclipse-ecj.db \
/usr/share/eclipse/plugins/org.eclipse.jdt.core_3.1.0/jdtCompilerAdapter.jar \
/usr/lib/eclipse/plugins/org.eclipse.jdt.core_3.1.0/jdtCompilerAdapter.jar.so
gcj-dbtool4 -m /usr/lib/eclipse/eclipse.db /tmp/eclipse-ecj.db \
