How do we prevent Enhancers to be applied on certain classes?

[Joel Grenon]

I'm using the latest HEAD version. My application was working well with mid-May builds. After pulling changes from Github, I get the following problem: 

I have an utility class, nothing to do specifically with Play, in an utils package in my app source folder. 

When I launch my application, I get the following error from LVEnhancer : 

Caused by: java.lang.UnsupportedOperationException: WIDE opcode is not handled yet

at bytecodeparser.analysis.Opcodes$9.init(Opcodes.java:392)

at bytecodeparser.CodeParser.parse(CodeParser.java:39)

at bytecodeparser.analysis.stack.StackAnalyzer.init(StackAnalyzer.java:71)

at bytecodeparser.analysis.stack.StackAnalyzer.analyze(StackAnalyzer.java:62)

at play.classloading.enhancers.LVEnhancer.enhanceThisClass(LVEnhancer.java:72)

This class should not be enhanced at all and thus the problem would be prevented. Is there a way to prevent enhancement of specific classes? Do I have to place these classes somewhere else? Can I annotate them somehow?

You can put your code in a static jar (inside your lib/ application
directory), but that’s not the most convenient solution.
Anyway that’s a bug you should report on lighthouseapp and which
should be fixed.

It is better to move to the 1.2.x branch for now. The master contains
a new byte-code enhancer that still fail on some cases.

Joel Grenon: Can you file a bug with details about how to reproduce this problem?

This makes it easier to follow the "case" and know when it's fixed.

Hi,

The very first version of BytecodeParser did not support the WIDE
opcode. I did release a version of BytecodeParser that supports it a
few days ago ; I will make a pull request to update it tomorrow.

The pull request 262 (https://github.com/playframework/play/pull/262)
should fix your problem :)

Pullrequest merged and http://play.lighthouseapp.com/projects/57987-play-framework/tickets/902-bytecodeparser-update#ticket-902-5 closed.

Now master branch should work for you again.
