I added a library under project properties -> "libraries" -> "Add JAR/Folder" which had an exclamation mark in its relative path: "..\libraries\Slick!\slick.jar". No error was given at this point. However this resulted in: - The jar file was navigable in the project pane, I could see all its classes - The ctrl-space hints show all the classes too - import lines were marked as "package abc.def does not exist" in the editor (with red squiggly lines) - No errors during build - Upon running, the applications fails with a java.lang.VerifyError Later on I tried adding the library as a global library (Tools -> Ant Libraries). This resulted in no error message however it cut off any text after the exclamation mark. For example a path of "D:\test!\test.jar" resulted in "D:\test".
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
