Mapscript API: for object manipulation, not object creation?

Doesn't appear to be. This is what I get in the logfile:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x400A3D89
Function=__libc_free+0x49
Library=/lib/tls/libc.so.6

Current Java thread:
         at edu.umn.gis.mapscript.mapscriptJNI.mapObj_insertLayer
(Native Method)
         at edu.umn.gis.mapscript.mapObj.insertLayer(mapObj.java:341)

Two possibly related items:

While the docs say the insert methods return the index at which the
object was inserted, the Java API doesn't seem to support this - it
supports a range of "insertFoo(foo, index)" methods.

Also, I notice that if I do a "make clean" in mapserver-4.4.2, I need
to do a "make interface" in mapserver-4.4.2/mapscript/java before I
can rebuild the Java API - which is then slightly different from the
one I get "out of the box". Mainly seems to be in the MS_ classes,
which define their statics as objects "out of the box" but ints after
a rebuild.
