JDK-7142086 - performance problem in Check.checkOverrideClashes(...)
Description
test/tools/javac/7142086/T7142086.java timeouts fairly consistently
on Valhalla. 

According to Maurizio, this is due to the handling of erasure which has become more complex in Valhalla. There's also perhaps a problem of using lambda 
expressions too much in sensitive parts of javac
Comments
Yes, the test looks incorrect for suggesting timeout=10 /* * @test * @bug 7142086 * @summary performance problem in Check.checkOverrideClashes(...) * @modules jdk.compiler * @run main/timeout=10 T7142086 */

This is a tier 1 test that just failed in production Mach 5. run=USER_SPECIFIED main/timeout\=10 T7142086\n Does this mean the test should run in under ten seconds? http://java.se.oracle.com/mach5//view/All/job/9-dev/1607/artifact/failureHistory/tier1-solaris-sparcv9.html

We will raise the time out factor for now and this ticket is created so the issue does not get forgotten.
