8382028: [lworld] gc/stress/gcbasher/TestGCBasherWithParallel.java fails with OOME

[lmesnik]

Test starts failing after https://bugs.openjdk.org/browse/JDK-8379695 [lworld] Update GCBasher to use value classes

The problem happened during file reading file and converting byte[] to Byte[] because it requires creation of 2 arrays of file length at the same time.
Verified that TestGCBasherWithParallel.java test pass with -XX:-UseCompressedOops.
The other tests (G1, Serial, ZGC) don't fail.
