@judovana for Platform class I linked it would need to be `@library /lib/testlibrary`, I think. Path is relative to `TEST.ROOT`. I accidentally posted example from hotspot, which has it's copy of that class placed a bit differently. Note that there is also another copy of whole test library in jdk (including Platform class), which came with jfr backport [1]. It is placed directly in `/lib` and uses package `jdk.test.lib`. This is a one you currently switched to. Tests in JDK 8 are unfortunately a bit messy.
