Xavier Fournet updated FLEX-34553:
----------------------------------
Description:
Intellij IDEA includes a feature that permits to compile many Flex project in
parallel. In some situations the compilation threads are stucks in the
MultiName class when querying the internal cache of MultiName. See the
following stack trace

The cache (MultiName#nsMap) is an HashMap that can be corrupted when many put
operations are done in parallel on it. I successfully patch the class to avoid
this problem with Flex 3 compiler.
