 Description  « Hide

The GroovyClassLoader is causing deadlock in certain situations with Groovy. The problem appears to be the deadlock is between these two:

for (Iterator iter = collector.getLoadedClasses().iterator(); iter.hasNext();) {
Class clazz = (Class) iter.next();
setClassCacheEntry(clazz);
}
protected void setClassCacheEntry(Class cls) {
synchronized (classCache) {
classCache.put(cls.getName(),cls);
}
}

and the call to

protected Class getClassCacheEntry(String name) {
if (name==null) return null;
synchronized (classCache) {
return (Class) classCache.get(name);
}
}
public Class loadClass(final String name, boolean lookupScriptFiles, boolean preferClassOverScript, boolean resolve)
throws ClassNotFoundException, CompilationFailedException
{
// look into cache
Class cls=getClassCacheEntry(name);
}

Here is the full thread dump from a Grails application:
