Mac - OS X Mavericks - cursor is slightly off / misaligned

System: MBP - OS X Mavericks
soapui: soapui-4.6.1

when writing groovy scripts i noticed, since the update to mavericks, that the cursor is shown slight off.

Example:
normally the cursor should be right behind the last quotes

String str = "hello world"|

but it is actually displayed like this (there are no additional white spaces, it just off)

String str = "hello world"  |
