RFR(XXS): 8213707: [TEST] vmTestbase/nsk/stress/except/except011.java failed due to wrong class name

[Zhengyu Gu]

Please review this trivial fix.

Currently, only Shenandoah experiences the failure, since other GCs run 
out Java heap memory, then the rest of test is skipped.

E.g.
pool[125131189]=new Object(); // elapsed 10.287s
pool[126306334]=new Object(); // elapsed 7.947s
Heap seems exhausted - OutOfMemoryError thrown.
Skipped: ExceptionInInitializerError: thrown OutOfMemoryError
Test passed.
