During the jdk8-b45 SWAT testing, we noticed there is an issue with b45 binary permission
In particular on Linux 32/64, solaris x86, Solaris x64, langtool regression test can not read sa-jdi.jar . As the result, the swat lang&tool regression fails to run

E.g of failing error when starting the jdk8-b45 swat langtool regression swat:

#97132: Failed to fetch remote checksum, remote feeder replied: Error while checksumming: FAILED Checksum calculation failed because of connector exception: FS exception <- File is not readable: /java/re/jdk/8/promoted/ea/b45/binaries/linux-i586/lib/sa-jdi.jar <
Same issue under /fastdebug dirs
