The following tests timed out on the same host in same task:

sun/security/pkcs11/Cipher/TestCICOWithGCM.java
sun/security/pkcs11/Cipher/Test4512704.java
sun/security/pkcs11/Cipher/ReinitCipher.java
sun/security/ec/TestEC.java

There's nothing obvious in the log files to indicate the reason
for the timeout. One thing that I noticed is that the 3 pkcs11/Cipher
tests ran at the same time and that was in overlap with the time
window for the sun/security/ec/TestEC.java.

TestEC.java:
start=Mon Aug 31 14\:36\:31 UTC 2020
end=Mon Aug 31 14\:44\:40 UTC 2020

TestCICOWithGCM.java
start=Mon Aug 31 14\:40\:20 UTC 2020
end=Mon Aug 31 14\:48\:31 UTC 2020

Test4512704.java
start=Mon Aug 31 14\:40\:20 UTC 2020
end=Mon Aug 31 14\:48\:31 UTC 2020

ReinitCipher.java
start=Mon Aug 31 14\:40\:20 UTC 2020
end=Mon Aug 31 14\:48\:31 UTC 2020

This overlap makes me wonder if these tests are somehow
interfering with each other.

Since these are Tier2 failures I would normally start this
bug as a P3, but these are the only sightings of these
tests failing in the CI.
