I found it's because I loose a semicolon at line 132. But why a semicolon could cause such a exception and eclipse coutld not found my loose of semicolon.
I upload an attachment which delete some useless code. I found it's because it has switch-case in lambda at line 96, eclipse is worked well when I delete this switch-case or lambda. With this lambda, when I delete the semicolon at this methoed, the exception is occured.
Created attachment 284423 [details] The source whitch delete useless code
I have the same error and it prevents me from saving the file, which should never ever, in no case happen to a user. Even if the code is really wrong, eclipse should never hinder the user from saving or editing the file. I get also a message box: >>> Save could not be completed. Try File > Save As... if the problem persists. Reason: Operation not supported for specified element type(s):Test.java [in de.mytest [in src(main/java [in Test]]] <<< Sometimes it even leads to corrupted metadata in the workspace, that prevent the user from opening the file later. For me that really is a showstopper as I have to revert the file to an old version and restore the metadata from a backup.
looks like a duplicate of Bug 567319 - can you please take one of the latest I builds and check whether this issue exists? thanks.
