IDEA 9.0.2 and Mac Java 1.6.0_19?

I'm seeing pretty significant weirdness in idea recently such as cache corruption (IDEA-54066), infinite indexing (IDEA-54420),  files appearing corrupt (IDEA-54458), etc.

I'm wondering if this might be related to java 1.6.0_19.  In particular, the mac pre-release.

Anyone else having issues?
