Hi David!
It's not a known issue. I had a short look into the code and the it happens
at the following line:
public Language resolveLanguage(String language) {
Language answer;
synchronized (languages) { // <- line 962
answer = languages.get(language);
// check if the language is singleton, if so return the shared
instance
if (answer instanceof IsSingleton) {
boolean singleton = ((IsSingleton) answer).isSingleton();
if (singleton) {
return answer;
}
}
// language not known or not singleton, then use resolver
answer = getLanguageResolver().resolveLanguage(language, this);
if (answer != null) {
languages.put(language, answer);
}
}
}
Can you raise a JIRA and attach a thread dump?
Best,
Christian
