Raymond Feng commented on TUSCANY-3268:
---------------------------------------
The documentBuilderFactory should be passed as non-null instance. Can you find
out the code on the stack that passes in the null documentBuilderFactory? We
should fix that at the root.

> Key: TUSCANY-3268
> URL: https://issues.apache.org/jira/browse/TUSCANY-3268
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Assembly Model
> Affects Versions: Java-SCA-1.5
> Environment: All
> Reporter: Hasan Muhammad
> Priority: Minor
>
> When we have a composite with properties and try to build it, it generates a
> harmless noise exception which can be avoided. The following is the exception
> java.lang.NullPointerException
> at
> org.apache.tuscany.sca.assembly.builder.impl.PropertyConfigurationUtil.evaluate(PropertyConfigurationUtil.java:73)
> at
> org.apache.tuscany.sca.assembly.builder.impl.PropertyConfigurationUtil.sourceComponentProperties(PropertyConfigurationUtil.java:146)
> at
> org.apache.tuscany.sca.assembly.builder.impl.BaseConfigurationBuilderImpl.configureSourcedProperties(BaseConfigurationBuilderImpl.java:828)
> at
> org.apache.tuscany.sca.assembly.builder.impl.BaseConfigurationBuilderImpl.configureComponents(BaseConfigurationBuilderImpl.java:100)
> at
> org.apache.tuscany.sca.assembly.builder.impl.ComponentConfigurationBuilderImpl.build(ComponentConfigurationBuilderImpl.java:65)
> The reason is the following block of code not checking for null
> PropertyConfigurationUtil.evaluate()
> Document document =
> documentBuilderFactory.newDocumentBuilder().newDocument();
> the documentBuilderFactory is null in this case, and we can simply check for
> it and if it is null, return null. We do check for the returned value is null
> or not in the method sourceComponentProperties, so no worries if we change
> this.
