Describe the bug

In Java, using "to" as a variable name will highlight it as if it was a keyword.

Expected Behavior

"to" should not highlight blue in the demo editor. Here are a list of Java keywords:

1. Open demo editor
2. Change language mode to "ace/mode/java"
3. Write some code that includes the word to e.g var to = "to"

Possible Solution

I rolled back to 1.30.0 and cannot reproduce it, but I can on 1.31.0. I think this is the change that introduces this:
