"Rerun failed jdk test cases in Grinder with jdk_custom target" didn't set BUILD_LIST

[pshipton]

In the build https://openj9-jenkins.osuosl.org/job/Test_openjdk11_j9_sanity.openjdk_s390x_linux_OpenJDK11/66/
The link for Rerun failed jdk test cases in Grinder with jdk_custom target
doesn't set BUILD_LIST properly. Although it does contain BUILD_LIST=openjdk, when you open the link the BUILD_LIST is set to functional.

For comparison, this build works fine https://openj9-jenkins.osuosl.org/job/Test_openjdk11_j9_sanity.openjdk_x86-64_mac_OpenJDK11/63/
Rerun failed jdk test cases in Grinder with jdk_custom target

The problematic link contains CUSTOM_TARGET=java/lang/ProcessBuilder/Basic.java#id0. The special character # breaks the URL link. The CUSTOM_TARGET value has to be encoded. See https://github.com/adoptium/aqa-tests/blob/master/buildenv/jenkins/JenkinsfileBase#L1054

@sophia-guo could you fix this? Thanks

Encoding is one thing. The reason it worked on mac is the test job on mac has default BUILT_LIST=openjdk while on s390 default BUILD_LIST=functional.

The other thing is jtreg won't work when specify test case suffixed by #id/d{1,}. Update the CUSTOM_TARGET to remove that and no need to encoding it.
