Description chne 2007-03-06 12:02:02 UTC 
if a uno methods accepts uno.Any as parameter and you fill this parameter with
java.lang.Object the Java-UNO-Bridge loops until stack overflow.

Example:

unoObject.method(java.lang.Object);
Comment 1 Stephan Bergmann 2007-03-06 12:53:33 UTC 
In jurt/com/sun/star/lib/uno/protocols/urp/Marshal.java:1.19, writeValue
recursively calls writeAnyValue, which uses TypeDescription.getTypeDescription
to find out that a java.lang.Object is of UNO type ANY, so recursively again
calls writeValue to write the same ANY value.

While it is a violation of the Java UNO language binding specification to pass
an instance of exact type java.lang.Object where a UNO ANY is required, it would
be nice if this were detected with some RuntimeException instead of a
StackOverflowError.
Comment 2 Stephan Bergmann 2008-08-18 12:59:12 UTC 
fixed as jurt/com/sun/star/lib/uno/protocols/urp/Marshal.java:1.20.8.1 with
tests at bridges/test/java_uno/any/TestAny.java:1.5.20.1 (see
<http://wiki.services.openoffice.org/wiki/Uno/Binary/Modules/bridges#Tests>) on
<http://eis.services.openoffice.org/EIS2/cws.ShowCWS?Path=DEV300%2Fsb93>
