| Description |
|
It seems that certain conditions may cause imaging to go haywire. To reproduce this:
Activity monitor under OS X shows that the org.apache.catalina.startup.Bootstrap process starts eating up CPU (see first attachment). If you click on one of the magnifying glasses on the page in order to get the high resolution images, the lightbox-like overlay does show up and works, but shows no images (see second attachment). Please refer to third attachment for a thread dump. |

Just for the record, as I don't think this matters here: also checked with latest available Java 5 version (1.5.0_24) on Snow Leopard with the same result. My impression was that the process consumes between 30-50% less CPU, though, but take that with a grain of salt. |
