jdcid:
status: Waiting
category: jaxb-xsd
subcategory: compiler
company: SEAGULL Software Systems
release: 1.0.1
hardware: x86
OSversion: win_xp
priority: 4
synopsis: NullPointerException running xjc version 1.0.2
description: FULL PRODUCT VERSION :
java version "1.4.2_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_02-b03)
Java HotSpot(TM) Client VM (build 1.4.2_02-b03, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]
EXTRA RELEVANT SYSTEM CONFIGURATION :
I'm running jaxb 1.0.2, not 1.0.1 (the only choice on the first page of the
bug reporting pages was 1.0.1!). I also tried it with the latest build
posted on java.net (jaxb-ri-20031125).
A DESCRIPTION OF THE PROBLEM :
With a particular xsd and xjb (see below), running xjc crashes with a
NullPointerException:
parsing a schema...
compiling a schema...
Exception in thread "main" java.lang.NullPointerException
at
com.sun.tools.xjc.generator.marshaller.MarshallerGenerator.generateMethodSke

at com.sun.tools.xjc.Driver.access$000(Driver.java:46)
at com.sun.tools.xjc.Driver$1.run(Driver.java:60)
Note that this same xsd and xjb compile just fine using jaxb 1.0.1.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run this xjc line:
xjc -b bindings.xjb configuration.xsd
with these files:
configuration.xsd:

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
not a crash..
ACTUAL -
see Description above
ERROR MESSAGES/STACK TRACES THAT OCCUR :
see Description above - full stack trace there.
REPRODUCIBILITY :
This bug can be reproduced always.
---------- BEGIN SOURCE ----------
see steps to reproduce above.

CUSTOMER SUBMITTED WORKAROUND :
I did discover by trial and error that if I remove this attribute:
fixedAttributeAsConstantProperty="true"
from bindings.xjb, then xjc works fine without crashing.
workaround:
