Dynamically upgrading java runtime environments with running applications
Disclosed herein are methods, systems, and processes to perform self-dependent upgrades of Java Runtime Environments (JREs). A request to update a plugin to a new version with a new configuration that includes a location to download a new upgrader-executable is received from a platform computing device at an endpoint computing device. The plugin is uploaded to the new version. The new upgrader-executable that includes an executable with an executable table executed by the plugin is downloaded from the location. The executable is used to halt execution of a JRE application (e.g., a Collector) and download JRE files required for the upgrade. The JRE application (e.g., the Collector) is then re-started with the new configuration, which can be rolled back if the upgrade is unsuccessful.
1. A method comprising:
performing, by a computing device:
executing a Java application in a Java Runtime Environment (JRE);
downloading a plugin from a platform computing device of a cloud-based platform;
executing the plugin to download an upgrader executable for upgrading the JRE;
executing the upgrader executable, wherein
the execution of the upgrader executable comprises:
halting the execution of the Java application, and
downloading one or more files for upgrading the JRE; and
re-starting the Java application after the JRE is updated with the one or more files.
2. The method of claim 1 , wherein
the plugin is downloaded in response to a request from the platform computing device.
3. The method of claim 2 , wherein
the request indicates a location where to download the upgrader executable.
4. The method of claim 1 , wherein
downloading the plugin comprises downloading an update to the plugin, and
the method further comprises updating the plugin to a new version based on the downloaded update.
5. The method of claim 1 , wherein
the plugin is a bundle plugin.
6. The method of claim 1 , further comprising the computing device:
validating the upgrader executable based on a signature file.
7. The method of claim 1 , further comprising the computing device:
launching a collector associated with the Java application;
determining that a first upgrade of the JRE is not successful; and
rolling back the collector to a previous running state based on the determination that the first upgrade is not successful.
8. The method of claim 1 , wherein
the cloud-based platform performs one or more cybersecurity services for a client network including the computing device.
9. The method of claim 8 , wherein
the Java application implements a collector that collects data about the client network or the computing device and sends the collected data to the cloud-based platform.
10. The method of claim 1 , wherein
the cloud-based platform is accessible over a public network, and
the plugin and the upgrader executable are downloaded over the public network.
11. A system comprising:
a computing device implemented by one or more processors and associated memory, configured to:
execute a Java application in a Java Runtime Environment (JRE);
download a plugin from a platform computing device of a cloud-based platform;
execute the plugin to download an upgrader executable for upgrading the JRE;
execute the upgrader executable to:
halt the execution of the Java application;
download one or more files for upgrading the JRE; and
re-start the Java application after the JRE is updated with the one or more files.
12. The system of claim 11 , wherein
the computing device is configured to download the plugin in response to a request from the platform computing device.
13. The system of claim 12 , wherein
the request indicates a location where to download the upgrader executable.
14. The system of claim 11 , wherein
the computing device is configured to update the plugin to a new version based on an update to the plugin downloaded from the platform computing device.
15. The system of claim 11 , wherein
the computing device is configured to validate the upgrader executable based on a signature file.
16. The system of claim 11 , wherein
the computing device is configured to:
determine that a first upgrade of the JRE is not successful, and
roll back the Java application to a previous running state based on the determination that the first upgrade is not successful.
17. The system of claim 11 , wherein
the cloud-based platform performs one or more cybersecurity services for a client network that includes the computing device, and
the Java application implements a collector that collects data about the client network or the computing device and sends the collected data to the platform.
18. One or more non-transitory computer readable storage media storing program instructions that when executed on one or more processors of a computing device cause the computing device to:
download a plugin from a platform computing device of a cloud-based platform;
execute the plugin to download an upgrader executable for upgrading a Java runtime environment (JRE);
execute the upgrader executable to:
halt execution of a Java application executing in the JRE, and
download one or more files for upgrading the JRE; and
re-start the Java application after the JRE is updated with the one or more files.
19. The one or more non-transitory computer readable storage media of claim 18 , wherein
the program instructions when executed on the one or more processors cause the computing device to download the plugin in response to a request from a platform computing device.
20. The one or more non-transitory computer readable storage media of claim 19 , wherein
the program instructions when executed on the one or more processors cause the computing device to determine a location where to download the upgrader executable from the request.
