Some virtual machines do not support Method.bytecodes():

Comment 1 Martin Entlicher 2007-11-22 15:29:27 UTC 
We need to check VirtualMachine.canGetBytecodes().
Comment 2 Martin Entlicher 2007-11-23 10:37:53 UTC 
The problem is fixed in trunk:

/shared/data/ccvs/repository/debuggerjpda/src/org/netbeans/modules/debugger/jpda/ExpressionPool.java,v  <-- 
ExpressionPool.java
new revision: 1.5; previous revision: 1.4
Comment 3 Richard Gregor 2007-11-25 07:29:20 UTC 
Increasing priority to P1 since this is important issue that should be fixed in NB 6.0 otherwise users will need to use
older version to debug the latest phone stack delivered by Sun.
Comment 5 Marian Mirilovic 2007-11-25 16:49:11 UTC 
Agreed with WTK team - this is stopper for NB 6.0.
