unable to build after being forced to update from 0.7.0-dev-1185 to 0.7.0-dev-1196

Due to issue #572 I was forced to update my project to teavm version 0.7.0-dev-1196. However, this now breaks the build:

Any ideas? According to history the method containsKey was always missing: https://github.com/konsoletyper/teavm/blob/master/classlib/src/main/java/org/teavm/classlib/java/util/TResourceBundle.java

However, with the old build (still in my local repo) it worked without this error.
