How do you replace endorsed directory in Java 9?
Solution 1
In JDK 9, you can use upgradeable modules or put the JAR files on the classpath.
The Java 9 migration guide states:
The
java.endorsed.dirs
system property and thelib/endorsed
directory are no longer present. Thejavac
compiler andjava
launcher will exit if either one is detected.
You would end up finding the error if any of these exists as :
<JAVA_HOME>/lib/endorsed is not supported. Endorsed standards and standalone APIs in modular form will be supported via the concept of upgradeable modules. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.
These endorsed-standards override mechanism was removed to attain Modular Run-Time Images and would now use the modular image.
A modular image is composed of modules rather than JAR files. Going forward, endorsed standards and standalone APIs are supported in modular form only, via the concept of upgradeable modules.
Solution 2
This is a specific solution but can probably be generalized. On System Version: macOS 10.14.6 (18G3020) Kernel Version: Darwin 18.7.0 I have OpenJDK 64-Bit Server VM (build 13.0.2+8, mixed mode, sharing) and java_ee_sdk-8u1 installed.
I encountered this error when executing xjc:
[foo@bar bin 14:47:27] sudo ./xjc
-Djava.endorsed.dirs=./../modules/endorsed is not supported. Endorsed standards and standalone APIs
in modular form will be supported via the concept of upgradeable modules.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.enter code here
I edited the last line in ~/glassfish5/glassfish/bin/xjc
to remove the -Djava.endorsed.dirs
bit:
BEFORE
exec "$JAVA" -Djava.endorsed.dirs="$AS_INSTALL_LIB/endorsed" -cp "$AS_INSTALL_LIB/webservices-osgi.jar:$AS_INSTALL_LIB/javax.xml.rpc-api.jar:$AS_INSTALL_LIB/jaxb-osgi.jar" com.sun.tools.xjc.Driver "$@"
AFTER
exec "$JAVA" -cp "$AS_INSTALL_LIB/webservices-osgi.jar:$AS_INSTALL_LIB/javax.xml.rpc-api.jar:$AS_INSTALL_LIB/jaxb-osgi.jar" com.sun.tools.xjc.Driver "$@"
After which ~/glassfish5/glassfish/bin/xjc
worked as expected

In Java 8 and prior there exists the mechanism to use an endorsed directory(java.endorsed.dirs), which is a collection of libraries which overrides JDK internal implementations.
How can I solve this in Java-9? As endorsed dirs where removed there?

Anders over 3 yearsYou don't, you use modules instead. Problems with endorsed and classpath is fixed with modules, becuase of several reasons.

Impulse The Fox about 6 years"Java versions higher than 8 are not supported by Tomcat 9" This is not true, look at the official site. It clearly says "8 and later".

Anders almost 4 yearsWhat is not supported after Java 8 is the switch
-Djava.endorsed.dirs=...
. It is not Tomcat that isn't supporting Java 9 and later.
