佐々木と申します。
mayaaのソースPageImpl.javaの140行目(下記プログラム1)の部分で、アプリケーションの全てのスレッドが停止してしまう現象が発生しました。
スレッドが止まった大元は、下記スレッドダンプ1、スレッドダンプ2の内容から、EngineImpl.javaの609行目で止まっている旨のスレッドダンプが出てました。
1年以上運用しているアプリケーションで、ライブラリのアップデートも行っていませんが、障害が内存していたのかと思いますが最近の一ヶ月で2回同障害が発生しました。
本障害を解消するための方法はありますでしょうか？
mayaa+HTMLの書き方に起因しているとか、ライブラリのアップデートで解消できるなど、情報がありましたらご教示ください。
よろしくお願いいたします。
