Description

Since upgrading http://media.io to Groovy 1.8.0, I very rarely get these exceptions:

groovy.lang.MissingMethodException: No signature of method: java.lang.String.shaHex() is applicable for argument types: () values: []
Possible solutions: size(), charAt(int), isCase(java.lang.Object), isCase(java.lang.Object), sleep(long), sleep(long, groovy.lang.Closure)
	at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:55)
	at org.codehaus.groovy.runtime.callsite.PojoMetaClassSite.call(PojoMetaClassSite.java:46)
	at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:112)
	at media.entities.Info$_getCleanName_closure1.doCall(Info.groovy:87)

The code in Info.groovy uses categories together with commons-codec and looks like this:

@EqualsAndHashCode(excludes = 'size,outputName,outputSize,format,progress,downloaded,tags')
class Info implements Serializable {
    
    private static final long serialVersionUID = 3L
    
    String name
...
    String getCleanName(String extension) {
        use (DigestUtils) { extension ? new StringBuilder(49).append(name.shaHex()).append('.').append(extension) : name.shaHex() }
    }
    
}

My guess is that this happens less frequently than every 50000 calls so it's hard for me to reproduce.

Any ideas? Could this be a thread-safety thing?
