A large html file with unclosed tag becomes unresponsive:
I opened a fairly large (50k) HTML file with an unclosed style tag in the section on IDEA 7.0.1. Once the file was open each character typed in the file took seconds to appear, until I managed to close off the style block.
The file in question contains a large ]]> construct.
Actually editing the file with the style block closed is responsive but a little slow. It appears to be causing a large number of garbage collections.
This is on a 4 core machine configured with an abundance of RAM.
