[Mac] TreeItem.getBounds() throws ArrayIndexOutOfBoundsException for labelled breakpoints with custom fonts

[SougandhS]

When attempting to edit a labelled breakpoint in the Breakpoints view, if the TreeItem has a custom font applied, calling TreeItem.getBounds() fails with:

!MESSAGE Unhandled event loop exception

java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

To Reproduce

1. Apply a custom label to a breakpoint.
2. Create a breakpoint at line 68 in BreakpointLabelAction,
3. Extract the tree.getBounds() out of try / catch block
4. Click on label again for that same breakpoint

Expected behavior
Currently a workaround is implemented but Inline editor should appear without exception.

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)
   Mac Os : 14.6 (23G80)

3. JRE/JDK version
   25

Version since
Eclipse or SWT version since when the behavior is seen [e.g. 4.23]
