[Bug java/13800] New: gcj fails to compile a class that extends a class in an external lib

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

gcj fails with:

  [javac] /var/ccm-devel/dev/richardl/cms/core/src/com/arsdigita/search/lucen\
e/TypeSpecificFilter.java:0: internal compiler error: tree check: expected clas\
s 'd', have 'x' (identifier_node) in check_inner_circular_reference, at java/pa\
rse.y:5212

when compiling a class that extends another class in an external library. In the
above case, TypeSpecificFilter extends Filter, which is not in the source tree,
but supplied in a JAR on the classpath.

I have confirmed this problem also exists with a class that extends
java.awt.Container:

    [javac] /var/ccm-devel/dev/richardl/cms/core/src/com/arsdigita/toolbox/rebo\
p/GenericComponent.java:0: internal compiler error: tree check: expected class \
'd', have 'x' (identifier_node) in check_inner_circular_reference, at java/pars\
e.y:5212

(To test this, I edited the respective class in the source tree to not extend
any class at all, and was able to continue with compiling the tree.)
