> 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).
> Here is the stack trace:
> {noformat}Exception in thread "main" javassist.CannotCompileException: by java.io.IOException: too much data

> 	at javassist.CtClass.toBytecode(CtClass.java:1279)
