Support duration is 6 years from the time that a major version of OpenJDK is first introduced in the particular version of Red Hat Enterprise Linux, or until the retirement date of the underlying version of Red Hat Enterprise Linux, whichever comes first. Red Hat provides long-term support for OpenJDK versions 7, 8, and 11. It is useful for understanding application behavior such as memory leaks, deadlock, and much more. wiki/OpenJDK Java is a registered trademark of Oracle and/or its affiliates. OpenJDK is the official reference implementation of Java SE since version 7.
#Openjdk 1.8 free
OpenJDK includes Mission Control 1 which is a tool suite for managing, monitoring, profiling, and troubleshooting Java applications. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java Platform, Standard Edition (Java SE). OpenJDK is tightly integrated with Red Hat Enterprise Linux and is supported on Windows.
#Openjdk 1.8 windows
A standalone Windows subscription is also available for purchase. OpenJDK support is included in Red Hat Enterprise Linux®, Red Hat Middleware, and Red Hat Application Runtimes
#Openjdk 1.8 upgrade
There are tools which can help you automate upgrade of JRXML templates, in case you actually need that.Red Hat is a member of the OpenJDK Governing Board and is the second largest contributor (behind Oracle). I also suggest you try to upgrade, as I'm not sure why your report would not work on newer versions of our library.
I suggest you first try to verify you need the isPrintWhenDetailOverflows="true", which is usually the main cause for infinite loops. In case the font does not exist, it is replaced with some default font that has different metrics and causes text to fit differently, triggering page breaks in a different way, hence the difference in behaviour. Your report seems to be using Arial, but do you actually have Arial installed on the machine or do you make it available using a JR font extension?
The difference in behaviour between the two versions of JDK is probably coming from the default fonts that are used, in case a font mentioned in the report is not found. There is probably a text field that overflows onto a new page, where some other elements need to be reprinted because of their isPrintWhenDetailOverflows=true, which in turn causes the text field to start too low and do not fit again, causing a new page break and again and again and again. The fact that the max pages governor limit was exceeded probably means your report enters an infinite loop trying to create new pages in the hope that the content will fit the next page. Please let me know if we can do something to make it work with Open JDK 1.8, as we cannot upgrade to higher versions of Jasper Reports Library, as our jrxml templates will not work with latest version of Jasper Library. I see a problem while generating the reports with Open JDK 1.8, the same works fine with Oracle JDK.
