There appears to be a memory leak when running validation definitly when compiling jsps but possibly other validation items as well.
To duplicate create a web project with 10-20 .jsps Run validation on them a few times while monitoring memory. It will climb until eventually you get an out of memory exception.
On web projects with 3 or 4 .jsps it’s not a big deal but when you get a project with 20-30 .jsps it becomes a problem.
