Java springboot application fails to connect to Valkey Cache using GLIDE

[alekhya538]

Hello,

We are trying to connect to AWS Valkey Cache (Serverless) from java springboot application (JDK17, springboot-version: 3.2.5).
Trying to use GLIDE as java client to connect to Cache and do Read/Write.

Here is the example code which I got from https://github.com/valkey-io/valkey-glide/blob/main/java/README.md.

private static void readCache() {
        log.info("In readCache");
        String host = "<host>";
        Integer port = 6379;

        GlideClientConfiguration config = GlideClientConfiguration.builder()
                        .address(NodeAddress.builder().host(host).port(port).build())
                        .build();
        log.info("config: " + config);

        try {
            GlideClient client = GlideClient.createClient(config).get();      <---- exception at this line
            log.info("client: " + client);

            log.info("PING: " + client.ping(gs("PING")).get());
            log.info("PING(found you): " + client.ping(gs("found you")).get());

            log.info("SET(cardNumber, 1234): " + client.set(gs("cardNumber"), gs("1234")).get());
            log.info("GET(cardNumber): " + client.get(gs("cardNumber")).get());

        } catch (ExecutionException | InterruptedException e) {
            log.error("Glide example failed with an exception: {}", e);
            e.printStackTrace();
        }
    }

Above code example is failing at line 'GlideClient client = GlideClient.createClient(config).get();'
Getting below error:
java.lang.NoClassDefFoundError: Could not initialize class glide.ffi.resolvers.SocketListenerResolver

Can anyone help how to fix this ?

Can you take a look?

[eifrah-aws]

This looks like as if the libglide_rs.so is not being loaded. Could run your application with -verbose:class (I am not sure how to use it inside spring)

[Yury-Fridlyand]

Hi
How do you add GLIDE dependency in pom/gradle config?

[alekhya538]

Here are the dependencies added in build.gradle

plugins {
     id "com.google.osdetector" version "1.7.3"
}

dependencies {
    implementation group: 'io.valkey', name: 'valkey-glide', version: '1.+', classifier: osdetector.classifier
    implementation 'io.valkey:valkey-glide:1.2.1'
}

[alekhya538]

@yipin-chen The log which I added after creating config, prints below:

config: GlideClientConfiguration(reconnectStrategy=null, databaseId=null, subscriptionConfiguration=null, advancedConfiguration=null)

Then this line (GlideClient client = GlideClient.createClient(config).get(); ) immediately throws exception,

`Error

Can you post your full list of dependencies please and sprint boot config if possible? I'm curious if something has a conflict with GLIDE's resourses (native lib).

Unfortunately, we cannot reproduce the issue with a sample spring boot app that we have.

I also noticed that I get below exception, the very first time I call the api after server restart.

`Handler dispatch failed: java.lang.UnsatisfiedLinkError: /tmp/nativeutils5539865577097/libglide_rs.so: Error loading shared library libgcc_s.so.1: No such file or directory (needed by /tmp/nativeutils5539865577097/libglide_rs.so)`

From second time onwards, it gives below exception.

`java.lang.NoClassDefFoundError: Could not initialize class glide.ffi.resolvers.SocketListenerResolver`

[Yury-Fridlyand]

Oh, that's very interesting. Could you verify please that you have libgcc_s on your machine?
Which OS is that? What is the GLIBC version (ldd --version)?

Thanks, that info could be very helpful!

Those are dependencies of GLIDE native components:

$ ldd target/release/libglide_rs.so
        linux-vdso.so.1 (0x00007ffed25f3000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007efc8978a000)

[alekhya538]

Thanks Yury. I have macOS Sequoia 15.0.

How do I check if I have libgcc_s ?

When I try ldd --version, I get zsh: command not found: ldd.

[Yury-Fridlyand]

I called a colleague with a mac to help there.
Do you have an mac with an intel CPU or apple silicon (M1 or so)?

[tjzhang-BQ]

@alekhya538 ldd isn't typically installed on macOS, if you installed gcc through homebrew, you can try:
sudo find $(brew --prefix) -name "libgcc_s*" to find libgcc_s, upon finding the path to libgcc_s you can run otool -L <path> to inspect the shared libraries and verify its version and dependencies

if homebrew wasn't involved I believe you can still try to locate the file in the GCC library directory by using the find command like find <lib directory path> -name "libgcc_s*"

[alekhya538]

@Yury-Fridlyand I have Apple M3.

[avifenesh]

@alekhya538
To my understanding, the cause is the library isn’t in any directory that Java expects libraries to be in.
Presumably since new macOS is using are not using .so anymore but .dylib.
Please verify gcc exists by running gcc --verison, if it doesn't, run brew install gcc.
If GCC didn't exist, and you installed, it might solve the issue.
New versions of macOS are no longer using .so but dylib so the issue might persist.
If it does, it's easily solved by creating a symlink.
Run ls -l /opt/homebrew/opt/gcc/lib/gcc/current/ and locate the libgcc_s.1.1.dylib -> sudo mkdir -p /usr/local/lib -> sudo ln -sf /opt/homebrew/opt/gcc/lib/gcc/current/libgcc_s.1.1.dylib /usr/local/lib/libgcc_s.so.1

Then in you application.properties add java.library.path=/usr/local/lib:/opt/homebrew/opt/gcc/lib/gcc/current or run the app using java -Djava.library.path=/usr/local/lib:/opt/homebrew/opt/gcc/lib/gcc/current -jar your-app.jar.

Which IDE do you use? If IntelliJ you can also go to Run -> Edit Configurations, and add to VM options -Djava.library.path=/usr/local/lib:/opt/homebrew/opt/gcc/lib/gcc/current.

Please let me know if it helped!

In the next release we will validate we release both for macOS 14 and both newer.

[Yury-Fridlyand]

As I found, gcc exists on macos OOTB. Is that possible that macos 15 doesn't have libgcc_s?

[avifenesh]

I checked on mine, and it was under brew. I didn't install it directly, but i assume it came with one of the packages.
So i guess if it's under brew it means it was installed.
