Please review the fix to this issue. Unused thread local StringCoding.Result is now wrapped with SoftReference, which can be GC'ed as needed. I confirmed it worked as expected with a test case (https://github.com/openjdk/jdk/blob/8b4e1e1cf8f5d753ed901406f73d67b21557fddb/test/jdk/java/lang/StringCoding/ResultCachedGCTest.java), but decided not to include it in this PR. This is because I purposefully chose the size of the byte array and max heap size which is fragile, and could become noise in a regression test run.
- Removed the test case.
