Re: [jdt-core-dev] Java9 Beta Branch
|
FWIW: I observe ClassFormatException triggered by AIOOBE using latest Y-build
plus HEAD of BETA_JAVA9 of JDT/Core running on and with jdk build 152.
Perhaps there are several subsequent changes in the class format?
This exception is caught, and after printStackTrace() ClasspathJrt$2.visitModule()
simply continues like normal.
I'm also seeing an NPE in ClassFile.generateModuleAttribute()
What's the current bug to track class format changes and related exceptions?

Yes, the class file format changed for module-info and we noted this with b149 and adjusted accordingly.
The latest patch should be able to handle b 149 and later (untested)
Did you install the latest patch from the market place? And all earlier versions of jdk9 need to be removed from the
installed JREs as well.

Mh, the original exception appears to be AIOOBE trying to retrieve the class name
from module-info.class. Has the class file format for module-info change?
Closest I could find at a quick scan:
http://mail.openjdk.java.net/pipermail/jigsaw-dev/2016-December/010383.html
Here Remi is only reacting to a class file change, but indeed he mentions
"setting the class name to null instead of 'module-info'"
Mh, he says NPE, I see AIOOBE <shrug>
What's the origin of that change? I don't know.

Hi,
What is the recommanded JDK9 build to give the Java9 support a try? I
gave b152 a shot but too me it looks like JDT is unable to process the
classfile because I see many many Exceptions like this
