RFR: 8146137: runtime/logging/ExceptionsTest.java fails on embedded and ARM test

[Rachel Protacio]

Hi,

Please review this fix for bug 8146137, where 
logging/ExceptionsTest.java was failing because of an optimized-away 
exception not being printed in embedded/arm, which does not use Tiered 
Compilation. Rather than fight with the platform, I've deleted the 
portion of the test looking for that compiled function's exception message.

To save time, I'll note that David Holmes and Coleen both reviewed the 
code offline already.

it's being confidential)
Passes JPRT testing.

Thank you,
