This PR fixes the StringIndexOutOfBoundsException, that occurs when an empty text is set to a Labeled, that previously contained a mnemonic.
The reason for the error is that the ``updateDisplayedText(double, double)``, which also updates ``containsMnemonic`` flag, was not invoked if the text was empty. The value of this flag was still ``true`` but the index of the mnemonic character inside ``MnemonicInfo`` had already been updated to -1. This led to the StringIndexOutOfBoundsException in the line 611. I fixed it by moving the call to ``updateDisplayedText(double, double)`` outside the if-clause, so that it is always called when the text is being laid out. This should not affect performance because the method already checks whether recalculation is required. If not, it exits quickly. --------- - [X] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - Fix StringIndexOutOfBoundsException Changes: https://git.openjdk.org/jfx/pull/2253/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=2253&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8389970 Stats: 60 lines in 2 files changed: 59 ins; 1 del; 0 mod Patch: https://git.openjdk.org/jfx/pull/2253.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/2253/head:pull/2253 PR: https://git.openjdk.org/jfx/pull/2253
