Description vicricker 2016-02-01 19:19:00 UTC

This bug was originally marked as duplicate of bug 229629, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE 8.1 (Build 201510222201)
VM: OpenJDK 64-Bit Server VM, 25.71-b15, OpenJDK Runtime Environment, 1.8.0_71-b15
OS: Linux

User Comments:
vicricker: A PHP project that I'm working on uses the naming convention of *.class for PHP classes.  Looks like NetBeans is trying to open them as Java Class files, and failing.

As a workaround, you can set the file association for class files to text/x-php5.

Options/Miscellaneous/Files/File Associations

Select 'class' from 'File Extension'
Set 'Associated File Type (MIME)' to text/x-php5 (or other)

Comment 3 Svata Dedic 2016-04-25 14:38:11 UTC

I see it as a relative corner case (with a workaround possible through a configuration). Mime resolution for application/x-class-file COULD possibly look for the magic header 0xcafebabe, but this would imply an overall performance impact  in java projects.
