UnsupportedOperationException when using examples/Makefile

[Thomas DANDELOT]

Hi,   When using Makefile from $JONAS_ROOT/examples, or scripts compile.sh from $JONAS_ROOT/examples/ everything goes OK till the command line : GenIC for JOnAS 2.2.7: Bean 'AccountExpl' generation... when I get a java.lang.UnsupportedOperationException  at java.lang.Throwable.<init>(Throwable.java:33)  at java.lang.Exception.<init>(Exception.java:20)  at java.lang.RuntimeException.<init>(RuntimeException.java:17)  at java.lang.UnsupportedOperationException.<init>(UnsupportedOperationException.java:17)  at java.util.AbstractList.add(AbstractList.java:33)  at java.util.AbstractList.add(AbstractList.java:22)  at org.objectweb.jonas_ejb.tools.GenICRemote.genBussinessMethodsOfInt(GenICRemote.java:145)  at org.objectweb.jonas_ejb.tools.GenICRemote.generate(GenICRemote.java:113)  at org.objectweb.jonas_ejb.tools.GenIC.genImplRemoteClass(GenIC.java:215)  at org.objectweb.jonas_ejb.tools.GenIC.main(GenIC.java:734)   This way I cannot try any of the examples contained in the jonas package. Anyone could help ? thanks                         Thomas DANDELOT
