> Test org.apache.harmony.test.reliability.api.nio.charset.DecodingModesTest from the reliability
suite hangs permanently on Linux x86; svn revision: 568905. The behaviour is similar to HARMONY-3666.
It seems to me that source of problem is a corrupted native memory pool, probably double free()
invocation.
