See Database changes for Java Batch in 18.0.0.1

There is a behavior change in java.util.zip.ZipFile.getEntry() from IBM SDK V8 SR4 FP10. With this release, the name of the ZipEntry instance returned from java.util.zip.ZipFile.getEntry() always ends with / for any zip directory entry. To revert to the previous behavior, set the system property jdk.util.zip.ensureTrailingSlash to "false". See here for details.
