| Some updates of JDK 1.8 (for example, JDK1.8.0_151) are affected by a known issue related to GZIP decoding. Until this issue is fixed, we recommend one of the following approaches: - Use either JDK1.8.0_144 or JDK1.8.0_077 updates. We have verified that these versions are not affected by the known issue.
- Alternatively, you can disable GZIP decoding for your product by following the steps given below. This will ensure that your product is not affected by the known issue.
- Open the
catalina-server.xml file from the <IS_HOME>/repository/conf/tomcat/ directory. Set the compression parameter (under each of the connector configurations) to false as shown below: | Code Block |

compression="off" |
- Restart the server.
