Vpc.fromLookup() throwing exception - CDK 1.5.0

[smoghal]

I have upgraded to CDK/Java 1.5.0 + 0.15.1 and now this basic code is not working:

VpcLookupOptions vpcLookupOption = new VpcLookupOptions.Builder().vpcId(<myVpcID>).build();
IVpc vpc = Vpc.fromLookup(this, "my-VPC", vpcLookupOption);

Same with this line:

VpcLookupOptions vpcLookupOption = new VpcLookupOptions.Builder().isDefault(true).build();
IVpc vpc = Vpc.fromLookup(this, "my-VPC", vpcLookupOption);

Exception:

This worked well before the latest CDK version.

What version were you using before when it was working? I'm trying to recreate the bug.

[rhboyd]

I can reproduce it and it also affects Vpc.fromVpcAttributes(...)

[RomainMuller]

This is caused by a bug in the JSII kernel, which has always been there but is triggered by a change in behavior with respects to object initialization in the Java runtime.

[RomainMuller]

Created issue on JSII side to track that: aws/jsii#753

[RomainMuller]

This would be fixed with the next CDK release that builds with jsii >= 0.16.0.

[rix0rrr]

Fixed in cdk 1.7.0.
