RFR: JDK-8196519: Incomplete classpath causes infinite recursion in Resolve.isAccessible

[Jan Lahoda]

Hi,

The problem here is that 
c.s.t.javac.code.Type.ErrorType.getEnclosingType returns "this", so if 
some code recursively analyses types and their enclosing types, it may 
get into trouble. In this case, it is Resolve.isAccessible which crashes 
with a StackOverflow.

It would be possible to break the infinite recursion in isAccessible, 
but it seems as not quite correct to return "this" from 
getEnclosingType. The proposal is to return Type.noType.

Bug: https://bugs.openjdk.java.net/browse/JDK-8196519
Webrev: http://cr.openjdk.java.net/~jlahoda/8196519/webrev.00/

How does this look?

Thanks,
