ICU-related Errors For Operations On Text

[mwu-tow]

General Summary

Calling length method (and possible others) on text leads to ICU-related Java errors.

There might be some race involved, as I can reproduce this with IDE package but not from slow debug builds.

Steps to Reproduce

Take IDE package. Start a new, default project.
Add node "foo bar baz".
While having the text node selected, open searcher and commit length method call.
Toggle visualization on text1.length.

Note that saving project and opening it again makes the issue go away.

Expected Result

Visualization gets an update with the value.

Actual Result

Visualization gets no updates.

Execution status reports error:
