[jboss-jira] [JBoss JIRA] Commented: (JASSIST-142) Javassist throws a CannotCompileException on the org.codehaus.groovy.runtime.ArrayUtil class

Robert Elliot commented on JASSIST-142:
---------------------------------------
Yes, exactly - the cause of the CannotCompileException is IOException("too much
data").
As I read the code it is imposing a limit on the size of the input stream of 8 * 4096 =
32KB, whereas as I understand it from here
http://java.sun.com/docs/books/jvms/second_edition/html/ClassFile.doc.htm... the class
file can be 64KB in length (probably more, as it's only the code_length attribute
that's restricted to 65536, but I can't claim to have understood the spec well
enough to know what that implies).
Javassist throws a CannotCompileException on the

Key: JASSIST-142
URL: https://issues.jboss.org/browse/JASSIST-142
Project: Javassist
Issue Type: Bug
Affects Versions: 3.14.0.GA
Environment: N/A
Reporter: Robert Elliot
Assignee: Shigeru Chiba
With Groovy 1.7.5 on the classpath the following snippet throws a
CannotCompileException:
{noformat}ClassPool classPool = new ClassPool();
classPool.appendSystemPath();
CtClass ctClass = classPool.get("org.codehaus.groovy.runtime.ArrayUtil");
ctClass.toBytecode();{noformat}
This is currently preventing me using PowerMock in a test case written in Groovy, which
seems a shame. It appears to be due to an artificial limit imposed in
ClassPoolTail.copyStream(InputStream, OutputStream).
