Description Nan Li CLA 2011-05-19 12:01:34 EDT 
Build Identifier: I20110512-2000

Define a custom converter for an ID mapping like this:

    @Id
    @Convert("BALABA")  
    @Converter(converterClass = MyConv.class, name = "CONV")
    private int id;

Once saving the java source, the following NPE is thrown and prevents the validation messages from showing up in the Problem view. This problem happens no matter whether the converter class is valid or not.

java.lang.NullPointerException
	at org.eclipse.jpt.common.core.internal.utility.jdt.AbstractJDTType.types(AbstractJDTType.java:171)

Full stack trace is attached.

Reproducible: Always

Same problem exists when defining a custom converter at Java entity level. Custom converters defined in mapping file don't have such problem.

From my testing, and from discussion with Brian, this bug is a result of a proposed fix for bug 346005.  As such, I don't think it would qualify as a bug since it doesn't exist in any development stream.

Please let me know if this is incorrect.

OK...I finally reproduced this exception.  I must not have had a converter class set previously.

Verified in Build R-3.3.0-20110607160810

Verified you can add custom converter(s) to id mapping without NPE errors.  See the link to view test steps for verification. http://wiki.eclipse.org/Dali_3.0_RC3
