Error in FieldAccessFilter

[mehdijk]

Hi
I work on HSQLDB 1.8.0.9 and make a Spoon model. When I try to get elements by a field filter, it makes NullPointerException error.
I use this command: List<CtFieldAccess<?>> fieldAccessList = rootPack.getElements(new FieldAccessFilter(ctField.getReference()));
and the trace of stack is as follows:
java.lang.NullPointerException at spoon.reflect.visitor.filter.VariableAccessFilter.matches(VariableAccessFilter.java:41) at spoon.reflect.visitor.filter.VariableAccessFilter.matches(VariableAccessFilter.java:26) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:58) at spoon.reflect.visitor.CtScanner.visitCtInvocation(CtScanner.java:483) at spoon.support.reflect.code.CtInvocationImpl.accept(CtInvocationImpl.java:48) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtBlock(CtScanner.java:280) at spoon.support.reflect.code.CtBlockImpl.accept(CtBlockImpl.java:46) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.visitCtMethod(CtScanner.java:539) at spoon.support.reflect.declaration.CtMethodImpl.accept(CtMethodImpl.java:60) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtClass(CtScanner.java:320) at spoon.support.reflect.declaration.CtClassImpl.accept(CtClassImpl.java:58) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtPackage(CtScanner.java:620) at spoon.support.reflect.declaration.CtPackageImpl.accept(CtPackageImpl.java:48) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtPackage(CtScanner.java:619) at spoon.support.reflect.declaration.CtPackageImpl.accept(CtPackageImpl.java:48) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtPackage(CtScanner.java:619) at spoon.support.reflect.declaration.CtPackageImpl.accept(CtPackageImpl.java:48) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:135) at spoon.reflect.visitor.CtScanner.visitCtPackage(CtScanner.java:619) at spoon.support.reflect.declaration.CtPackageImpl.accept(CtPackageImpl.java:48) at spoon.reflect.visitor.CtScanner.scan(CtScanner.java:146) at spoon.reflect.visitor.QueryVisitor.scan(QueryVisitor.java:67) at spoon.reflect.visitor.Query.getElements(Query.java:70) at spoon.support.reflect.declaration.CtElementImpl.getElements(CtElementImpl.java:345)

Did you check: ctField.getReference() != null ?

[mehdijk]

Yes, I check. It is not null
