Description David Green

2009-04-29 01:16:47 EDT

I'm seeing a pinwheel (hung UI) for 0.5-1.5s every time I save a Java file.  Is this possibly related to the new API baseline tooling?  This problem does not occur when using Eclipse 3.4.2

Using:

pre. 
Version: 3.5.0
Build id: I20090421-0930
Eclipse Java Development Tools 3.5.0.v20090421-0800-7q87FEeFIiLwrHbdz0WFbcqe

IMO, it looks like a duplicate of bug 273308. Could you make a try with a more recent I-build (>= I20090426-2000) and let us know if you still observe this problem?
TIA

Comment 2 David Green

appears to be resolved in I20090428-0100
