[jdk17u-dev] RFR: 8261404: Class.getReflectionFactory() is not thread-safe

[María Arias de Reyna]

This is my first contribution. I am backporting https://bugs.openjdk.org/browse/JDK-8261404

Tier1 tests are passing on my computer, with the exception of one that was failing before trying to apply the changes:


Finished running test 'jtreg:test/lib-test:tier1'
Test report is stored in build/linux-x86_64-server-release/test-results/jtreg_test_lib_test_tier1
