BCEL with jdk 1.5beta2

Hi,
I have trouble analyzing  class files generated with sun's JDK 1.5 beta2.
a LDC_W.getType() seems to always throw the following exception:

Exception in thread "main" java.lang.RuntimeException: Unknown or
invalid constant type at 34
at org.apache.bcel.generic.LDC.getType(LDC.java:148)
...

Inevitable,  a javap -v <class> on the constant pool offset printed 
(34 in the example above) has something like this
--
...
const #11 = Asciz   com/sun/corba/se/spi/logging/LogWrapperBase;
...
const #33 = Asciz   setThrown;
const #34 = class   #11;    //  com/sun/corba/se/spi/logging/LogWrapperBase
--

i.e. CP entry #34 seems to be redirected to #11. it looks like the getType() 
is unable to handle this redirection.

is this something new to the 1.5 class file format or the 1.5b2 compiler ?
Is there a known workaround ? All the classes I am trying to analyze are in
rt.jar. thanks.
