RFR(S): 8149462: revert changes for 8149186

[Michael Haupt]

Dear all,

please review this fix.
Bug: https://bugs.openjdk.java.net/browse/JDK-8149462
Webrev: http://cr.openjdk.java.net/~mhaupt/8149462/webrev.00

The changes introduced for JDK-8149186 [1] led to nightly build failures and reproducible crashes in test262parallel on Linux. A fix is proposed [2] but is pending investigation. To stabilise the nightly builds, the changes that introduced the errors should be reverted for the time being.

Thanks,

Michael
